Disturbance Rejection
for Permanent Magnet
Synchronous Motors
13.1 Introduction
A permanent magnet-synchronousmotorhas many excellent features such as asimple
structure, high torque-to-current radio, high power density, low noise, and friendly
maintenance [151]. Due to these advantages, PMSM has gained widespread accep-
tance in numerical control machine tools, robots, aviation, and so on. Linear control
methods such as the proportional-integral (PI) control scheme are already widely
used in PMSM systems due to their easy implementation. However, since PMSM
system is a nonlinear system with unavoidable ...
