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.
Abstract:
Aiming at the robustness analysis problem of linear optimal control system, this paper proposes to study the dynamic relationship between system parameters and stability margin by taking the system stability margin as the calculation object, so as to obtain a visual description of the robustness of the system. This method uses Matlab’s control function programming program to continuously solve the algebraic Riccati equation, and obtains the change trend of system stability margin with parameter perturbation, and then displays it by computer graphing. The simulation results show that it has practical value for the analysis of the optimal control system with accurate mathematical model.
