摘要
针对线性最优控制系统的鲁棒性分析问题 ,提出以系统稳定裕度作为计算对象 ,研究系统参数与稳定裕度之间的动态关系 ,从而得出系统鲁棒性的直观描述 .这一方法采用Matlab的控制函数编制程序 ,连续求解代数Riccati方程 ,得出系统稳定裕度随参数扰动的变化趋势 ,再由计算机作图显示 .仿真结果表明 ,它对具有精确数学模型的最优控制系统的分析有实用价值 .
For the purpose of analyzing robustness of linear optimal control system,this article introduces a method that takes the stability margin as an object calculated and researches its dynamic relations with parameters of this system,then comes up with a direct description for the system robustness This method makes use of the control functions of Matlab to program and continuously resolves Riccati algebra equation to preview the trend of system stability margin changed by the parameters and shows results with diagrams in computer Simulation result shows that it is practical for analysis of optimal control systems with accurate math model
