A speed controller that considers the effects of system dead time and parameter variations is presented. An indirect field-oriented induction motor drive is implemented, and its dynamic model is found, using a stochastic approach. A two-degree-of-freedom speed controller is designed to match the prescribed speed command tracking and load regulating specifications. Since the performance of the closed-loop controlled plant is greatly 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 performance both in speed command tracking and load regulating characteristics is achieved
