Abstract
In this paper, a speed controller considering the effects of system dead time and parameter variations for indirect field-oriented induction motor drives is presented. First, an indirect field-oriented induction motor drive is implemented, and its dynamic model is found based on the stochastic approach. Second, a two-degree-of-freedom speed controller is designed to match the prescribed speed command tracking and load regulating specifications. Since the performances of the closed-loop controlled plant are much influenced by the presence of the inherent system dead-time and parameter variations during wide-range operations, a dead-time compensator and a model following controller are proposed to enhance the robustness of the two-degree-of-freedom speed controller. The simulated and experimental results show that good control performances both in speed command tracking and load regulating characteristics are achieved.
