Abstract

In recent years, the interior permanent magnet synchronous motor (IPMSM) has become increasingly popular for use in high performance drive (HPD) applications due to desirable features such as high torque to current ratio, high power to weight ratio, high efficiency, low noise and robust operation. As a consequence, the control of the IPMSM for use in high precision industrial drives has received heightened attention. This proposed research is directed to develop and implement a complete and practical vector control scheme for the IPMSM to be used in such applications. -- This thesis presents the control of the IPMSM at rated speed and below, in the constant torque mode, by use of the maximum torque per ampere (MTPA) mode of operation utilizing an innovative Taylor series approximated approach. Coupled with this method is the development of a simplified fuzzy logic controller (FLC) based speed controller that maintains high performance standards while reducing complexity and computational burden. The performance of this proposed technique is evaluated by simulation as well as by experimental results. A comparison is made, in simulation, between a more conventional FLC based control technique with id=0 and the proposed simplified FLC with MTPA approach. -- The complete vector control scheme is implemented in real-time using a digital signal processor (DSP) controller board in a laboratory 1 hp interior permanent magnet synchronous motor.
