摘要:
最优控制设计中所采用的数学模型与实际系统总有一定差别,据此设计出的控制参数与实际并不完全相符.针对这一问题,提出了分析线性最优控制系统稳定鲁棒性的一种方法.利用Matlab的专用控制函数工具,分析了系统中某些环节时间常数、放大倍数等参数变动以及加权矩阵的选择对系统鲁棒性的影响.仿真结果表明,该方法可具体分析出每个局部对系统稳定性的影响程度,有利于进行系统维护,保证系统安全.
Abstract:
The mathematical model used in the optimal control design is always different from the actual system, and the control parameters designed according to this are not completely consistent with the reality. To solve this problem, a method is proposed to analyze the robustness of the stability of linear optimal control systems. Using Matlab’s special control function tool, the influence of parameter changes such as time constant and magnification in some links in the system and the selection of weighted matrix on the robustness of the system was analyzed. The simulation results show that the proposed method can specifically analyze the influence of each part on the stability of the system, which is conducive to system maintenance and system safety.
