A New Type of Sensorless Induction Motor Direct Torque Control System

Article Preview

Abstract:

According to motor installation mechanical sensor inconvenient problem put forward new speed identification method, from adaptive control principle and extended kalman filtering algorithm principle of the two different observer is applied to induction motor direct torque control, and analyses the research and comparison, find out their advantages and disadvantages. Using Matlab/Simulink construct the system model and the simulation, and the results show that in the load change, noise suppression, etc is better than that of EKF MARS, in the state observation, the MARS is better than that of EKF.
