介绍一种响应速度快、无超调、鲁棒性强、抗干扰性能好的控制策略——ＰＤＦ（Ｐｓｅｕｄｏ－Ｄｅｒｉｖａｔｉｖｅ－Ｆｅｅｄｂａｃｋ）控制，并提出一种设计ＰＤＦ控制器的新途径。数字仿真结果表明，同传统的Ｃａｓｃａｄｅ－Ｓｙｓｔｅｍ法（亦称Ｐｈｅｌａｎ法）和Ｓｉｎｇｌｅ－Ｓｙｓｔｅｍ（亦称陈留法）一样，在有功率元件输出功率限制的情况下，用这种新方法所设计的控制器能够使系统实现较好的响应性能。 This paper introduces a Pseudo-Derivative-Feedback (PDF) control strategy with fast response, no overshoot, strong robustness and good anti-jamming performance. A new approach to designing a PDF controller is presented. The numerical simulation results show that the controller designed by this new method is the same as the traditional Cascade-System method (also known as Phelan method) and Single-system (also known as Chen-li method) Enables the system to achieve better responsiveness.
