Điều khiển động cơ xoay chiều ba pha có nhiều tham số bất định sử dụng bộ ước lượng tốc độ

Abstract. This paper investigates and proposes a three-phase AC motor control system combining

an adaptive speed estimation method and control algorithms using neural networks to deal with

uncertain parameters in dynamic models of the motor such as the rotor’s resistance, as well as the

friction coefficient and load changes when the system operates. Some simulation results on MatlabSimulink are provided to show the efficiency of the proposed speed estimation and speed control

method.

Key words. Induction motor, speed estimation, motor control, neural networ
