摘要
在基于Smith算法的基础上,将模糊控制器与传统的PID控制器结合,设计了一种模糊PID控制器。该控制器通过输入偏差信号和偏差信号的变化率,对PID的参数进行实时整定,并将控制过程中出现的纯滞后环节,移到闭环回路之外,从而消除纯滞后现象,提高系统的稳定性。保证了系统具有良好的动态性能。
Smith-based algorithm based on fuzzy controller with the traditional PID controller, the design of a fuzzy PID controller. The controller through the input signal and the deviation of the error signal changes in the rate of the PID parameters Real-time tuning and move the course of time delay link in the control, to the clused-loop. So as to eliminate dead time, and increase the stability of the system. To ensure that the system has a good dynamic performance.
