针对异步电动机传统起动方法的不足,本着增大起动转矩、减小起动电流的目的,通过对模糊控制器进行分层次结构设计,在加入变比例因子控制以后,通过不断地调整比例因子,使电动机达到最佳输出状态,改善了系统的动态性能。实验表明,这种控制与PID控制相比,其综合性能指标较佳,且系统建模简单,因此发展潜力很大。 Aiming at the insufficiency of the traditional starting method of asynchronous motor, this paper designs the fuzzy controller hierarchical structure by increasing the starting torque and reducing the starting current. After adding the variable factor control, by adjusting the scale factor, The motor to achieve the best output state, improve the dynamic performance of the system. Experiments show that, compared with PID control, this control has better comprehensive performance index and simple system modeling, so there is great potential for development.
