提出了一种新的积分二次约束(IQC)框架下的网络控制系统设计方法。考虑了两种类型的网络诱导时变时延，即测量时延和激励时延。提出了一种新的时延调度脉冲(DSI)控制器，该控制器同时利用被控对象状态和IQC动态以及实时网络诱导的时延信息进行增益调度反馈控制。利用动态IQC与时钟相关存储函数相结合的方法，对所得到的脉冲闭环系统进行了稳健的稳定性分析。在分析结果的基础上，通过指定分段线性存储函数，将所提出的DSI控制器的综合条件建立为有限个数的线性矩阵不等式，并通过凸优化有效地求解。最后，通过在直流电机系统中的应用，验证了该设计方法的有效性和优越性。
This paper presents a new design approach for networked control systems under the integral quadratic constraint (IQC) framework. Two types of network induced time-varying delays, that is, measurement delay and actuation delay, are considered. A novel delay scheduled impulsive (DSI) controller is proposed, which utilizes both plant state and the IQC dynamic state, as well as the real-time network-induced delay information for gain scheduling feedback control. Robust ${\mathcal L}_{2}$ stability analysis of the resulting impulsive closed-loop system is performed using dynamic IQCs combined with a clock-dependent storage function. Based on the analysis results, the synthesis conditions for the proposed DSI controller are established as a finite number of linear matrix inequalities by specifying a piecewise linear storage function, which can be solved effectively via convex optimization. Finally, an application to a dc motor system demonstrates the effectiveness and advantages of the proposed design approach.
