Robust control of a brushless servo motor via sliding mode techniques

Abstract

Robust control of a synchronous machine via sliding mode techniques is tackled in some detail. Such control laws are well suited for the electric power converter. However, high frequency commutations are avoided due to the mechanical systems. Various recent schemes are studied and operated to derive control solutions which are technically feasible. Robustness is studied with respect to rotor flux uncertainties and to stator resistance which varies with the temperature of the motor.
