Intelligent Optimization Design of Induction Motor Direct Torque Control without Speed Sensorless
摘要
Abstract
In some special working environment, the speed of motor should be controlled accurately. In order to reducing rotor speed ripple caused by general regulator of direct torque control system in low speed, a new PI regulator based on fuzzy neural network was designed,and the modified speed regulator has fast self-regulating, micro over modulation characteristic. Aiming at improving the stability of MARS speed observer in low speed, a model reference speed-adaptive observer based on artificial neural network was designed, and the modified observer has good tendency , static characteristic. Simulation results showed that intelligent optimization design makes direct torque control system a obviously improved performance, better robustness and self-adaptive.关键词
