碩士 === 龍華科技大學 === 機械系碩士班 === 93 === The main research of this paper is induction motor speed control, we propose Weighting PI/PID Parameter Tuning Method design speed controller for induction motor speed control and compare to the 「Modified Model Reference Adaptive Systems」speed controller. The speed estimator also use of the Model Reference Adaptive Systems to identify rotor speed. System simulation program is written by Matlab® M-file. The experiment carried out via PC and peripheral module. The simulation and experiment tests under speed sensor and speed sensorless to verify the feasibility of the theory. The Weighting PI controller is better in precision than the Modified Model Reference Adaptive Systems under sensor condition, but the after is better under sensorless condition.
