AbstractThis thesis describes the speed control for surface mounted and interior type permanentmagnet synchronous motor using nonlinear adaptive control methods First based onadaptive input output feedback linearization control IOFLC method an adaptivenonlinear control is derived to obtain the reference voltage command of a three phase two level SV based PWM inverter which feeds the motor This control is capable ofstabilizing and increasing the robustness of the drive system control against parametersuncertainty and external load torque disturbance In the second stage the samecontroller is designed using adaptive backstepping control approach In this method approximately all the system electromechanical parameters are estimated online while in IOFLC only electrical parameters are estimated In both motors the maximum torque per ampere control strategy is considered Moreover a sliding mode observer is developed for estimating the motor speed and rotor position The observer uses parameters which are estimated online by the nonlinear adaptive controller The effectiveness and validity of the proposed controller approach are verified by computer simulation t iflljf Ii ts l lt
