SPEED CONTROL OF PERMANENT MAGNET …
I SPEED CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR USING EXTENDED HIGH GAIN OBSERVER By Abdullah Ahmad Alfehaid A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of Electrical Engineering Master of Science 2015 ii ABSTRACT SPEED CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR USING EXTENDED HIGH GAIN OBSERVER By Abdullah Ahmad Alfehaid Feedback linearization is used to regulate and shape the SPEED of a surface mount PERMANENT MAGNET Synchronous Motor (PMSM). An extended high gain observer, which is driven by the measured position of the PMSM s rotor, is also used to estimate both the SPEED of the motor and the disturbance present in the system to recover the performance of feedback linearization.
The design of the speed controller and the extended high-gain observer is based on the nominal parameters of the PMSM. The disturbance is assumed to be unknown, and time-varying but bounded. Stability of the output feedback system is shown. ... Improvements to SMC have taken place to reduce chattering such
