| Abstract |
Current control of permanent magnet synchronous motor is designed for optimal robust
performance under both uncertainties in stator parameters and variation of operating speed. To avoid the
conservatism inherent in many robust control approaches, and to admit a exible choice of optimization
criteria, the design is carried out with help of a genetic algorithm. The controller is composed of two
SISO PI-controllers and a static feedback decoupling network that minimizes the interaction between the
d- and q-axes uniformly across the parameter uncertainty range, and across the speed range. Remaining
interaction is eliminated by a simple on-line adaptive cancellation. This results in a practically perfect decoupling
in the stationary case, and better than a guaranteed worst performance under all circumstances. |
