10 PID SIMULATOR SIMCET Software (SIMulator for Certification, Education and Testing)

11 SIMCET PID TUNING SIMULATOR SIMCET is a PID Tuning Real-Time Simulator for training. You can mimic real PIDs from a DCS/PLC graphic/screen on to a PC and even match process dynamics precisely. Copy JPGs from your DCS/PLC/SCADA, mimic process dynamics and build a simulation resembling your plant on a SIMCET screen- all in minutes! It is simple, fast, compact, can be downloaded and used in just 10 minutes! You can also practice PID tuning on the simulator. Additionally, SIMCET can test your PID tuning skills using unique, novel online real-time tuning tests that are randomly generated. Use SIMCET to train new employees faster and better, like never before. 11

12 TRAIN, TEST, CERTIFY & QUALIFY YOUR PROCESS CONTROL ENGINEERS AND TECHNICIANS Each plant has many PID Controller Loops. PID tuning skills are very important. Simcet helps to improve PID Tuning Skills. User can tune loops on a PC instead of real plant. Simcet provides real-plant tuning environment. Fearlessly tune loops, drive them unstable or sluggish, put in Manual/Auto and learn PID tuning. 12

13 NEW & UNIQUE PID TUNING TRAINING SYSTEM USING SIMCET 2 3 GRADING Engineer or DCS Technician PID Tuning TESTING on Simulator Supervisor Checks Tuning Score from Simcet (Performance). If good score, person is Qualified to tune loops in Control Room. Otherwise he must Practice and Re-Test. 1 PID Tuning PRACTICE on Simulator 4 Secretary maintains PID tuning test Scores for new and current engineers. Everyone must take test every year to maintain good skills. 13

14 REACTOR TC SIMULATION Fearlessly Play with PID Control, drive Unstable to Learn Tuning like never before You learn faster since you can run PID simulations in faster time speed than real life. Very slow loops can be made to run fast. See results of tuning changes soon instead of after minutes or hours! Setpoint Change You could rarely do this in real plant, but you can on Simcet Real-time Simulator PiControl Solutions Company Copyright

15 After all PID Tuning Tests are Taken, Final GRADE SHEET is generated 15

16 COPY JPG OF DCS GRAPHIC Make a screen shot of DCS/PLC operator graphic Incorporate into Simcet Build dynamic model using actual plant data 16

17 READ PLANT DATA FROM EXCEL OR OPC TO IDENTIFY PROCESS DYNAMICS Read PID data from Excel or OPC.

18 FROM DCS SCREEN (JPG) TO SIMCET ON PC Port PID Loops dynamics and DCS graphic into Simcet Real-time simulator trend (behaves like the real process and the real PID in DCS or PLC) 18

19 SIMCET ADAPTIVE CONTROL AND NONLINEAR DYNAMICS Every process is nonlinear to varying extents. SIMCET allows adaptive tuning and nonlinear dynamics to accommodate: Startup conditions Low/Medium production rate Maximum production rate Process upset/abnormal conditions Grade transitions Different process relationship due to different catalyst, raw material or equipment Instead of high effort, cost and difficult modeling using rigorous engineering models, SIMCET offers a novel, modern way of simulating process with dynamics and adaptive adjustment based on actual process data. The simulator model prediction fidelity is higher. Time to build simulator is much shorter and costs are far lower. 19

20 PID TUNING OPTIMIZER AND DCS-BASED APC DESIGN PITOPS Software

21 WHAT IS PITOPS? It is process control software for chemical plants and universities. It identifies transfer functions. It optimizes PID tuning parameters. It helps to designs APC (Advanced Process Control) inside the DCS or PLC. It is an Industrial Tool for the Control Room and a Training Tool for Research and Teaching in Colleges.

22 PITOPS IS A MAJOR NEW INVENTION Pitops identifies multivariable transfer functions with closed-loop data (no step-tests) in just minutes! Pitops tunes single PIDs, Cascade and Slave PIDs precisely meeting plant needs. Pitops can be used develop APC (advanced process control) systems inside the DCS, PLC or SCADA systems much better and cheaper than MPC (model predictive control).

23 PID TUNING ILLUSTRATION PPM Gas Composition AI SP (Setpoint) AC PPM Gas Composition Cascade PID Controller Gas Phase Reactor Slave Flow Controller FC FI Gas Flow Indicator Gas Flow Into Reactor Gas phase composition is controlled by a cascade PID (AC) analyzer controller, whose OP (output) manipulates the SP (setpoint) of a slave flow controller. We illustrate the tuning of the AC which has slow and complex dynamics.

24 READ PLANT DATA FROM EXCEL OR OPC We specify the Excel Filename Pitops then reads PID PV, the Controlled Variable Pitops also reads PID OP, the Manipulated Variable First, Pitops reads data from Excel or OPC.

25 TRANSFER FUNCTION PARAMETERS The BLUE trend is the Transfer Function Model Prediction See transfer Function Parameters Identified: Dead Time=18 minutes Process Gain=32.8 Time Constant=35.8 minutes Complete Closed-Loop Data from normal plant operation (No Step Tests like conventional methods)!

26 PID TUNING OPTIMIZATION Now we proceed to PID Tuning Optimization First, set the CV range, in our example, range of the AC (analyzer controller) Next, set the MV range, the output range of the AC

27 OPTIMIZE PID TUNING Next, click on Optimize PID Tuning See Calculated Optimum PID Tuning Parameters See the optimized PV Response Notice the SP Change, Blue Trend Examine the AC (PID) OP Output Trajectory

28 THE ENTIRE PROCESS OF PID TUNING INCLUDING TRANSFER FUNCTION IDENTIFICATION TOOK Only 3 Minutes and 10 Clicks And it was so Easy, Fast and Convenient! No intrusive step tests, but just used closed-loop data from normal operation

29 MULTIVARIABLE IDENTIFICATION Pitops can process multivariable inputs and outputs (MIMO systems). See a three input multivariable identification below. Pitops identifies Three transfer functions simultaneously using complete Closed-Loop data. MV#1 (Input #1) MV#2 (Input #2) MV#3 (Input #3) Transfer Function #1 Transfer Function #2 Transfer Function # CV (Output) See next slide showing plant data and Pitops identification CV is Overheads Product Purity MV#2 is Reflux MV#1 MV#2 CV MV#1 is Column Feed MV#3 MV#3 is Reboiler Steam

30 FEEDFORWARD CONTROL, CONSTRAINT OVERRIDES, MODEL-BASED CONTROL, INFERENTIAL CONTROL Pitops is not only a transfer function identifier and PID tuning optimizer but has the functions to design, implement and tune Feedforwards, Constraint Control Schemes, Model- Based Control and Inferential Control Schemes. Feedforward Control Production Rate Maximizing APC Constraint Override Control Inferential and Model- Based Control

31 IMPROVE MPC (DMC/RMPCT) PERFORMANCE SOLUTION TO TWO PROBLEMS: Over 65% base-level PIDs poorly tuned MPC/DMC models show slower dynamics because of poorly/sluggishly tuned primary PIDs Steady state and dynamic component in MPC models may be off by 50% to 200% As a result poor control action by DMC/RMPCT Lack of awareness of problem No simple solutions for the new and inexperienced engineer. Error in DMC/RMPCT models due to small steps, nonlinearities and many other reasons Pitops can identify multi-input closed loop models Help to improve DMC model Tremendous improvement in DMC controller performance 31

32 WITH PITOPS AND SIMCET Port your DCS operator graphics into SIMCET Use PITOPS to mimic real plant dynamics into SIMCET. Train, test and certify your engineers and technicians like never before. Build DCS-based APC: In a remarkably short time With minimal intrusive and disturbing plant tests Increase Production Rates Reduce Operator Mistakes and Shutdowns Run Plant Smoother Save 2-10% profits. 32

33 ONLINE CONTROL QUALITY MONITORING APROMON Software (Advanced Process Monitoring)

34 ONLINE CONTROL QUALITY MONITORING- APROMON SOFTWARE Plants have PID loops Process dynamics change PIDs and APC systems need to be monitored Control room staff cannot watch all controllers daily Online monitoring software is essential Less than 15% of plants use monitoring software Big opportunity is missed Monitoring software: Generates daily report (identifies bad PIDs and APCs) Sends online /text alerts when control deteriorates Proactive versus Reactive Maintenance APROMON control monitoring product is compact, easy to use and can monitor as many as 5000 PIDs 34

35 WHAT WILL HAPPEN AT YOUR PLANT TOMORROW IF THIS HAPPENS Signal is normal here Signal freezes here (instrument or communications failure) How would your operator know there is a problem?? Operator would not know until much later when process upset took place. 10 min If you had Apromon, operator would have received an ALARM here (after only 10 minutes!) 35

36 ARE YOU AWARE YOUR CONTROL VALVES ARE SLOWLY GETTING DESTROYED? Control valve may be moving erratically like this one. How would you know?? There are control valves in your plant. Apromon would have alerted and helped you to make control valve movement smoother This control valve will wear out fast and cost you replacement maintenance costs. Apromon helps to: Identify Noisy PV signals Advises you to put PV filtering Warns of excessive Derivative action Increases control valve life Improves control action Average savings US$275,000 per 36 year

39 APROMON CONTROL MONITORING BENEFITS EXAMPLES Which loops are not controlling well? Which loops are oscillating? Which loops have matching frequencies? Which control valves are not working well? Which control valves are moving excessively? Which loops need proportional adjustment? Which loops need integral adjustment? Which loops need derivative adjustment? Which loops need filter adjustment? What is onstream factor of the loops? Which loops do the operators intervene most? Which loops have instrument signal problems? And many other diagnostic assistance tips for the control room engineer and technician. 39
