A positian controller considering the effects of systea dead-time and parameter variations for Induction motor servo drives Is proposed in this paper. First a OSP-based computer controlled indirect field-oriented induction motor servo drive is isplemented and its flynamlc model at noailnal case is estimated from measurements. Based on this model, an integral plus proportional (IP) controller is quantitatively designed to match the prescribed position tracking specifications. Then a dead-time compensator (DTC) and a simple robust controller (BC) are designed and augmented to reduce the effects of system dead-time on the stability and the performance degradation due to parameter variations. The prescribed drive tracking specifications can be preserved under parameter variations. Bather good load regulating response can also be obtained. Some eaqierimental results are provided to demonstrate the effectiveness of the proposed controllers.
