航机陆用动力装置控制系统的一种设计方法

本文以内部模型控制(IMC)算法为出发点,阐述了航机陆用动力装置的控制系统的设计方法。文中讨论了内部模型的原理及特点,滞后系统辨识的特殊性及解决方法,最后又把IMC控制器与经典反馈系统的控制器比较。并对内部模型系统进行了仿真计算,用IMC算法设计的系统可简便地通过盏线调整一个参数来实现ISE最小及较好的过渡过程性能指标。

A DISIGN TECHNIQUE OF CONTROL SYSTEM OF AIRCRAFT POWER PLANT USED FOR GROUND INSTALLATIONS

A design technique of control system of aircraft power plant used for ground installations is presented in this paper on the basis of internal model control (IMC) algorithmic approach. The principles and salient features of Internal Model Control, the specific characteristics and its solving method of the lag system identification are disenssed. At last, the IMC controller and the classical feedback system controller are compared and the simulation calculation of IMC system has been made. Through discussion, it can be seen that minimum ISE and better performance index of transient process can be easily realized in the system designed with IMC algorithmic approach through on-line adjusting one parameter. The IMC algorithmic approach is a good design technique.
