摘　　要：本文给出一种新型过渡过程自适应ＰＩＤ控制器。对控制信号而言，它是一个没有任何相位落后的ＰＩＤ控制器，Ｒ高频为一放大器，低频为积分器，中频段为ＰＩＤ。对谐波信号而言，高频段为一相位超前５１．８５°的放大器，低频段为一相位落后仅５７．５１°的积分器，中频段为ＰＩＤ，但相位［－５７． ５１°，５１．８５°］。它的控制职能的转换是随着过渡过程的发展而自动完成的，刚好满足优化控制对控制器提出的要求，称它为过渡过程自适应ＰＩＤ。最后讨论它在多目标优化控制中的应用。This paper gives a new adaptive PID controller with leading phase. For the control action it's an adaptive PID controller without any phase lag, but there is an amplifier in the high frequency,an integrator in the low frequency,and a PID only in the medium frequency. For the harmonic input it is still an adaptive PID controller, but there is an amplifier with leading phase 51. 85° in the high frequency,an integratol only with lagging phase 57. 51° in the low frequency,and a PID with phase [- 57. 51°, 51. 85°] only in the medium frequency. It can automatically change itself control function according to the transient development. So that we also named it as adaptive PID controller of transient process. Finally,discuss its applications in the multiobjective optimum control system [MOOCS].
