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。 In this paper, the internal model control (IMC) algorithm as a starting point, described the aircraft landing power plant control system design method. In this paper, the principles and characteristics of the internal model are discussed. The particularities of the identification of lagged systems and their solutions are discussed. Finally, the IMC controller is compared with the controller of the classical feedback system. And the internal model system is simulated. The system designed by IMC algorithm can easily adjust the ISE parameters to achieve the minimum and best ISE transition performance index.
