基于单神经元PID的直流脉宽调速系统研究

摘要

针对传统直流调速系统存在因PID控制器参数固定而导致调速性能差的问题,提出了基于单神经元PID的双闭环直流脉宽调速系统的设计方法,即采用单神经元PID控制器替代传统的转速PI调节器,并用S函数编写该控制器的算法程序.Matlab仿真结果表明,基于单神经元PID的双闭环直流脉宽调速系统具有较快的响应速度和较强的抗干扰能力,调速性能得到了较好的改善.%In view of problem that conventional DC speed-regulation system has poor speed-regulation performance because of fixed parameters of PID controller,a design method of double closed loops DC PWM speed-regulation system based on single neuron PID was proposed.The conventional PI speed regulator was replaced by single neuron PID controller,and its algorithm program was written by Sfunction in Matlab software.The Matlab simulation results show that double closed loops DC PWM speedregulation system based on single neuron PID has fast response and strong anti-interference ability,and its speed-regulation performance has been improved.
