摘要
针对常规PID控制器不能满足非线性、时变系统的控制要求的问题,本文将自适应控制思想与PID控制器相结合,合成一种自适应PID控制解决方案,并设计了一个自适应PID控制器。该方案运用专家控制策略,自动整定PID参数。仿真结论表明,在系统参数不确定或者发生变化时,该控制器的控制效果明显优于常规PID控制器。
In view of the problem that routine PID controllers can not satisfy the control requirements for nonlinear time-variant systems, the adaptive control is used in PID controllers and a self - adaptive PID controller is synthesized. The design utilizes an expert control strategy to adjust the PID parameters automatically. The simulation results show that this controller provides an evidently improved control capability, compared with routine PID controllers.
