【Abstract】 An uncertainty predictor based on grey theory was presented to overcome the shortcoming of the traditional feedback linearization control scheme model, which needs precision model. The designed grey feedback linearization control system was implemented in an indirect field-oriented induction servo motor to track speed commands. In the proposed control system, a grey uncertainty predictor adjusted the lumped uncertainty existed in the induction servo motor to follow a feedback linearization control law on line. Simulation result indicates that the control scheme has good tracking control performance and robustness to uncertainty.更多还原
