摘　　要：Ziegler—Nichols稳定边界法整定PID控制器参数 ,系统的跟踪性能不好 ,超调量较大。针对这种情况 ,本文给出了一种二自由度PID实现 ,可以较好的克服这个不足之处。Simple PID controller tuned by Ziegler-Nichols tuning formulas based on the ultimate gain and ultimate period method cannot track set-point changing and is aggressive,To overcome these deficiencies,this paper gives a designing of two degrees of freedom.Extensive simulations have shown that the proposed method can improve largely capability of PID controller

关 键 词：PID控制器 PID控制 边界法 二自由度原理 仿真
