Abstract

In this work the regulation problem for a permanent magnet synchronous motor, in presence of disturbances and parameter uncertainties, is considered. The disturbance is due to the load torque, which varies sinusoidally with known frequency by unknown amplitude. The motor parameters are supposed unknown or slowly varying. The reference and disturbance signals are supposed to be generated by what is usually called exosystem. The regulator derived ensures the asymptotic tracking of a given angular velocity in such a condition. The performance of the structurally stable regulator are compared with a regulator based on the nominal system parameters
