研究了一类具有不确定时延的多包传输网络控制系统的保性能控制问题.在传感器数据传输采用静态调度策略的情况下,在控制器端用对象模型来估计对象的状态,根据接收到的传感器数据更新模型的相应状态,将多包传输网络控制系统建模为具有不确定性的线性离散周期系统.根据周期系统理论和矩阵不等式方法,推导了多包传输网络控制系统保性能控制律存在的条件,给出了保性能控制律的设计方法,利用PENBMI软件包求解双线性矩阵不等式约束的优化问题可得到次优保性能控制律和次优性能指标.仿真例子验证了设计方法的有效性.

The problem of guaranteed cost control for a class of multi-packet transmission networked control systems with uncertain short time-delay was studied.Under the condition of static schedule of sensor data transmission,a model was introduced in the controller node to predict the plant state,its state Wilts updated using the received sensor data,then the multi-packet transmission networked control system was modeled as a linear discrete periodic system with uncertainties.The existence condition of guaranteed cost control law Was derived according to periodic system theory and matrix inequality method,and the design method of guaranteed cost controller Was also presented.The suboptimal guaranteed cost control law and suboptimal cost index was obtained through solving optimize problem constrained by bilinear matrix inequalities using PENBMI software.The simulated results by an example show the validity of the proposed method.
