Abstract Vector control s a speed control technque used to obtan fast and accurate speed control of nducton motor. Speed sensors degrades relablty hence speed sensorless speed control s proposed. Ths work presents accurate electrcal parameter estmaton such as flux, torque, theta and speed usng reduced order extended Kalman flter based nducton motor control s proposed. The Kalman flter s based on the mnmzaton of the estmaton error and t s sutable for obtanng hgh accuracy estmates of state varables and model parameters and elmnatng measurement noses. Here no need of speed, torque, flux, rotor poston and stator voltage sensors, alternatvely the stator current wll be measured by three current transformers (CT s) wth supportng of mathematcal equatons. The proposed method has some advantages of savng computaton tme n comparson wth the full order extended Kalman flter. The proposed work s mplemented by a hardware usng DSPIC30F4011 controller and smulated wth help of MATLAB SIMULINK R010a verson. Keywords.Vector control, Extended Kalman flter, Current transformers, Speed sensorless, Coordnate transformaton 1. Introducton The nducton machne s the heart of the most wdely used form of electrcal AC drve. Inducton motor can be consdered as the workhorse of the ndustry. Inducton motors are classfed nto sngle phase nducton motor and three phase nducton motor based on gven nput supply. Three phase nducton motors are the most common motors used n ndustral control systems and commercal applcatons. In the past, nducton motors were preferred only for constant speed applcatons. Adjustment of speed of nducton motor was very dffcult and also needs hgh cost. But the rapd growth n power electroncs and semconductor technology results, many knds of nducton motor varable speed drves have been developed and now the nducton motors are very good alternatve for varable speed applcatons. The robustness, low cost, the better performance and the ease of mantenance make the nducton motor advantageous n many ndustral applcatons for general applcatons. A fast and controlled speed response from an nducton motor s obtaned most effectvely f the prncple of vector control s used. Vector control method s also called as feld orented control method. Vector control method s vald for both steady state as well as dynamc state condtons. In vector control t controls not only the ampltude, frequency but also ther phase angle. The man dsadvantages are the huge computatonal capablty and accurate measurements of the motor parameters are requred. In the drect vector control, nformaton about the actual values of the magntude and poston of the rotor flux and rotor speed s necessary. Vector controlled nducton motor drves are wdely used n the ndustral applcatons where hgh performance, lke fast torque and speed responses, are demanded. The man concept of vector control s to decouple the control of nducton motor's flux and torque va coordnate transformatons and to control not only the ampltudes of current and flux but also ther phase angle. The Kalman flter s based on the mnmzaton of the estmaton error and t s sutable for obtanng hgh accuracy estmates of state varables and model parameters and elmnatng measurement noses. A lot of researches are carred out to develop accurate speed estmaton technques. To obtan accurate, hgh performance lke fast torque, speed responses and more relable n three phase nducton motor drve system the vector control method has been proposed. The work s manly focused on speed sensorless speed control of three phase nducton motor usng vector control technque through reduced order extended Kalman flter. For ths purpose of modellng and desgn of nducton motor drve I am developng hardware and smulatng wth help of MATLAB SIMULINK R010a verson.. Modelng of Inducton Motor The IM mathematcal model may perhaps be explaned n the rotatng drect quadrature (d-q) frame as gven below where d and q, V d and V q, ω r, T L,ψ rd and θrepresents stator currents, stator voltages, rotor speed, load torque, drect-axs rotor flux, and flux angle, correspondngly. Parameter τ r = L r / R r ndcates the rotor tme constant and σ = 1 L m L s L r sgnfes the leakage magnetc coeffcent. 44

Desgn of Reduced order Kalman flter In ths approach, the three-phase stator currents are the soltary essental measurements, and these are converted from the three-phase reference frame to a dphase reference frame, and subsequently to the frame of the rotatng feld (d-q) as gven below: d = cos θ 3 a + cos θ 3 π b + cos θ + 3 π c q = sn θ 3 a sn θ 3 π b sn θ + 3 π c Where a, b and c sgnfes the three-phase stator currents, correspondngly and θ represents the estmated flux angle. V d, V q and θ are engaged as feedback to the reduced order extended Kalman flter. (3) Ψ est = (φsd + φsq ) At ths moment, wth the stator flux and the dphase reference frame from the stator currents, together wth the motor poles P, Torque s estmated dependng on the equaton below. T est = 3 P(φsd. sq φsq. sd) (5) Where,φsd and φsq represents the stator flux, sd and sq represents the stator currents Estmated Flux angle can be computed from the equaton gven below. θ = tan 1 φsq (6) φsd 3.1 Speed sensorless speed estmaton Wth the ntenton of estmatng the sensor less speed, the estmated stator flux has to be transformed nto rotor flux dependng on the magnetzng nductance n addton to the secondary nductance per phase. φrd = L m L r φsd; Square of rotor flux, φrd + φrq φrq = L m L r φsq... (7) For the purpose of determnng the speed of rotor feld, the acheved rotor flux has to be transformed nto α, β coordnates, by means of the transfer functon. Speed of rotor feld = (φrd φrβ) (φrq φrα) 3.

The obtaned d-q frame voltages V sd and V sq are subsequently gven as feedback to the sldng mode observer to approxmate the necessary electrcal constrants of the nducton motor. Ths evaluaton s performed by takng smply stator current. Inverse park transformaton s exploted to transform the dphase voltage (V sd and V sq ) nto a three phase voltage (V a, V b and V c ) whch s then taken as nput to the Space Vector Pulse Wdth Modulaton. 4. Block dagram and ts explanaton The fgure1 shows the complete block dagram of the proposed work, t conssts of three phase dode brdge rectfer, DC lnk capactance flter, three phase VSI nverter, reduced order extended Kalman flter (sldng mode observer). The operaton of the proposed system s managed by reduced order extended Kalman flter (sldng mode observer) and Pulse Wdth Modulaton. In ths proposed system, there s no necessty for speed, torque, flux, poston and also voltage measurements. The sldng mode observer has the capacty to perfectly approxmate the speed, flux, theta and torque wth the help of the phase currents sensng alone. The sngle phase nput ac voltage s rectfed to dc voltage by..(1) means of dode rectfer and.(13) then the DC lnk voltage VRdcR s gven as nput to the three phase voltage source nverter. The three phase VSI converts dc supply nto three phase ac supply. The SPWM control technque to get the desred output from VSI. Then ths three phase ac supply s gven to stator of the three phase nducton motor. Intally the three phase stator currents are measured through current transformers and then they are converted nto two phase by axs or co-ordnate transformaton usng phase angle(θ) whch s generated byreduced order extended Kalman flter and then these two phase stator currents RsqR and RsdR are gven as nput to the reduced order extended Kalman flter. The reduced order extended Kalman flter uses recursve algorthm and t takes these two phase stator currents as nput and calculates the estmated speed, estmated flux, and estmated torque and phase angle(θ). It compares the reference flux and estmated flux and the result error s processed through a PI controller and t gves the flux controllng component VRsdR. smlarly the reference speed and estmated speed are compared and the result error s processed through a PI controller and t gves the reference torque and agan these reference torque and estmated torque are compared and the result error s processed through a another PI controller and t gves the torque controllng component VRsqR and these flux controllng component VRsd Rand torque controllng component VRsq Rare taken feedback to the reduced order extended Kalman flter. 46

The drver unt uses snusodal PWM technque compares the carrer sgnal(trangular wave) and the gven three phase reference sgnal(snusodal wave) and generates the PWM pulses of wdth vared accordng to the three phase reference voltage sgnal and these PWM sgnals are gven to the MOSFET swtches n the VSI for swtchng acton. As the three phase reference voltage s vared accordng to the set speed and n turn PWM sgnal pulse wdth s vared accordng to the three phase reference voltage and n turn the output of VSI s vared accordng to the PWM pulses and n turn the nput of the motor s the output of VSI and n turn the speed of motor s vared as the nput of the motor s vared, hence we wll get desred set speed and ths type the speed of three phase nducton motor s controlled. 4.
