摘要
为了解决网络控制系统中时延不确定而造成的系统控制的困难,提出了一个增广矩阵模型。在该模型的基础上把时延造成的系统的不确定性转化为系统矩阵的不确定项,然后在鲁棒镇定控制律设计方法的基础上,根据该不确定项结构的特殊性,提出比传统鲁棒控制律设计方法具有较小保守性的稳定控制律设计方法。仿真例子说明该控制律设计方法的有效性。
To resolve the problems brought by the delays exist in the networked control systems, an augmented matrix model for the networked control systems is presented, and based on this augmented matrix, the uncertainty generated by the delays is transformed into the systems martrix' uncertain items, and based on the particularity of the structure of the uncertain items, a stabilizing controller designing method is presented, which is similar to but has less conservatism than the tradictional robust control law designing method. The simulation examples show the feasibility of the proposed method.
