摘要
针对异步电机直接转矩控制系统PID转速调节器的适应性、鲁棒性及抗干扰性较差的问题,提出了基于智能神经元PID转速调节器的异步电机直接转矩控制方法。智能神经元PID转速调节器采用2个神经元控制器进行设计,同时实现了控制器参数的在线调整,磁链调节器和转矩调节器分别采用滞环调节器进行设计。仿真结果表明,基于智能神经元PID的异步电机直接转矩控制系统能快速跟踪参考转速变化,具有很强的抗干扰能力、自适应能力和较强的鲁棒性。
In view of worse adaptive ability,robustness and anti-interference ability existed in direct torque control system of asynchronous motor based on conventional PID speed regulator,a new direct torque control method of asynchronous motor based on intelligent neuron PID speed regulator was proposed. The intelligent neuron PID speed regulator was designed by two neuron controllers,and parameters of this speed regulator could be adjusted online. The flux regulator and torque regulator were designed by hysteresis regulator respectively. The simulation results show that the direct torque control system of asynchronous motor based on intelligent neuron PID speed regulator can rapidly track the reference speed changes and the control system has stronger anti-interference performance,adaptive performance and stronger robustness.
