摘要
目前大多数反馈控制系统的控制器采用比例、积分、微分控制算法(PID).本文对控制系统进行了深入分析,并采用伪微分反馈(PDF)控制算法对直流电机速度和位置进行伺服控制,进行了计算机仿真以及伺服控制系统实验.结果表明.PDF控制系统对阶跃输入响应性能好.对外界负载干扰抑制能力强,对被控系统参数变化不敏感.
Most current feedback systems seem to have been designed around the proportion .integral and derivative type of control algorithm (PID).This paper is concerned with the Pseudo-Derivative-Feedback. controller(PDF) for the design of feedback control system. Simulations and experiments are performed for controlling the speed and position of a DC servo-motors machanism. Comparison with the results of P1D controller shows that the PDF approach is superior in response to step change-input,able to reject disturbances due to step-changes imposed by external loads and insensitive to parameter variations of the controlled system.
