摘要：
The paper deals with the adaptive control of an electrical drive intended for positioning applications. The regulator is based on a pole-placement technique and an on-line identification algorithm. The results of a previous work made by the authors are reviewed and a more accurate modelling is worked out by including a term accounting for the torque; to this aim a static feedforward element is designed and added to the control scheme. The limit on the motor current provided in actual systems is also taken into account, and a desaturation strategy is proposed and tested. A further improvement of the performances is obtained by a dynamical change in the saturation limits. A number of simulations are presented to illustrate the performance of the system.
