EEF EEF dvanced PID Improved with Fuzzy Omron's EEF temperature controllers combine advanced PID control with Fuzzy Logic control to improve responsiveness to external process disturbances, events that cause a clear offset between the process and set temperatures. Omron's advanced PID control and Fuzzy Logic control operate in parallel. The PID control operates during normal conditions, while the Fuzzy Logic control operates only when there has been an external disturbance to the process. The startup and stable state operation is identical to Omron's conventional PID controllers. The of the EEF is the sum total of the of the PID and fuzzy control functions. oth PID and fuzzy scale parameters can be set automatically by autotuning, or may be manually set. There are three fuzzy parameters users can set, and the illustrations show the impact of each one: FUZZY INTENSITY Fuzzy intensity (FU) determines the impact of the Fuzzy Logic section of the control algorithm, on the final control percentage. This parameter is the nominal value which can be set from 0 to %. Default setting is 0%. When set to 0%, fuzzy control will have no influence, and the unit will function as a PID controller (like Omron's EEX). s this value is increased, the corrective actions taken by the controller will become larger. The FU value should be increased in applications where quicker neutralization of a process disturbance is required, and/or overshoot on the recovery from the disturbance needs to be further minimized. Small Fuzzy intensity Large FUZZY SCLE Fuzzy Scale (FUS) controls the magnitude of error "membership function". This value corresponds to what the controller should consider to be a "large" error and can be set in a range of 0. to. (C or F). Default setting is 0. For every sample the controller compares the present error to FUS value in order to make a subjective decision about the size of the error. Decreasing this value makes the controller more sensitive to error, and will decrease the response time for returning the process back to set value. Large FUS Small FUZZY SCLE Fuzzy Scale (FUS) controls the rateofchange "membership function". This value corresponds to what the controller should consider a "large" rate of change, and can be set in a range from 0.0 to. (C or F) per second. For every sample the controller compares the present rateofchange to the FUS value in order to make a subjective decision about the size of the change. Decreasing this value will make the controller more sensitive to change. ecause small changes in this value can cause a large increase in oscillations, best results can usually be achieved by manually setting FU and FUS and leaving FUS at the autotuned value. Large FUS Small COMINED EFFECTS OF FUZZY DJUSTMENTS Correcting large overshoot without hunting with an increase in Fuzzy Intensity Eliminating small overshoot and lengthening stabilization time by decreasing Fuzzy Scale Eliminating large overshoot and shortening hunting time by increasing Fuzzy Intensity and Fuzzy Scale
