Study on Three-phase Asynchronous Motor Based on Fuzzy Adaptive PI Vector Control

Three-phase AC asynchronous motor is a high - order, multivariate, strong-disaster non - linear system. To solve the problem that the performance of vector control system of asynchronous motor is worse due to the variation of motor parameters and load fluctuation. In this paper, the fuzzy adaptive PI control algorithm based on vector control is used to control the operation of three-phase asynchronous motor, which makes the speed control system have strong adaptability and robustness. The researches show that fuzzy adaptive PI vector control algorithm has the advantages of fast response speed and small overshoot. The experimental results show that this algorithm is effective and it can realize real-time control of the motor, which has certain practical value.
