摘要
针对一类含有不确定参数的网络控制系统(NCS),研究网络中存在时延与丢包情况下的鲁棒?∞控制问题.构造一个新的Lyapunov-Krasovskii泛函,并基于改进的Wirtinger不等式推导出闭环NCS渐近稳定且满足?∞性能的充分条件,该条件能得到比已有文献保守性更小的结果.给出线性锥补算法以实现次优鲁棒?∞控制器增益的求解.最后通过多个数值实例验证了所提出方法的有效性.
The robustH∞control of a class of uncertain networked control systems with network-induced delay and data packet dropout is studied. A new Lyapunov-Krasovskii functional is proposed, and sufficient conditions for guaranteeing the robust stability and H∞ performance of the considered system are derived based on an improved version of Wirtinger inequality. The derived conditions can lead to less conservative results than existing corresponding ones. A cone complementary linearisation(CCL) algorithm is given to solve the suboptimal robust H∞ controller gain. Numerical examples are given to illustrate the effectiveness of the proposed methods.
