对于一类具有非线性扰动的不确定奇异系统,研究了其鲁棒镇定问题.假定不确定参数是范数有界的,非线性扰动函数满足Lipschitz条件.以线性矩阵不等式的形式给出了不确定系统鲁棒稳定的一个判定准则.基于该准则,设计了一些状态反馈控制器使得闭环系统鲁棒稳定.最后,通过仿真实例验证了所得结果的正确性. For a class of uncertain singular systems with nonlinear disturbances, the robust stabilization problem is studied. Assuming that the uncertain parameter is a bounded norm and the nonlinear perturbation function satisfies the Lipschitz condition, a linear matrix inequality is given Based on this criterion, some state feedback controllers are designed to make the closed-loop system robust and stable.Finally, the simulation results verify the correctness of the results obtained.
