研究了带有扇形非线性和不完美测量的离散时间系统的输出反馈镇定问题.所提出的控制律模型同时考虑了网络诱导的时滞、丢包和信号量化.通过选取恰当的李亚谱诺夫泛函,得到了依赖于网络状况且具有较少保守性的稳定条件.据此,以一种非线性矩阵不等式的方式给出了静态输出反馈镇定控制器的存在性准则,该非线性矩阵不等式可以利用所提出的锥补线性化(cone complementary linearization,CCL)方法求解.最后提供了一个数值例子验证了方法的有效性.
The output feedback stabilization for discrete-time systems with sectorial non-linearities and imperfect measurements is studied. The proposed control law model considers both network-induced delay, packet loss and signal quantization. By choosing the appropriate Lyapunov , A stable condition that depends on the network condition and has less conservativeness is obtained. Based on this, the existence criterion of the static output feedback stabilization controller is given by means of a nonlinear matrix inequality. The nonlinear matrix Inequality can be solved by the proposed method of cone complementary linearization (CCL). Finally, a numerical example is provided to verify the effectiveness of the method.
