摘要
采用Lyapunov方法设计了独立于模型的标量增益的线性控制律和矩阵增益的非线性控制律,从理论上分析和证明了在该控制律作用下的闭环系统是全局渐进稳定的;在Matlab环境下对不同条件和不同形式的控制律进行了仿真,给出了不同控制律下的控制系统性能指标,仿真结果表明设计的控制律对模型参数摄动和外界干扰具有较好的鲁棒性。
The scalar gain linear control law and the matrix gain nonlinear control law which are inde- pendent of the model are separately designed using the Lyapunov method. The global asymptotic stability of the closed-loop control system in the laws is analyzed and proved theoretically. The control laws in different conditions and forms are simulated in Matlab, and the performances of the control system under different laws are given. Simulation result indicates that the designed control system has better robustness to the model uncertainties and the external disturbances.
