一种基于模型的输出反馈网络化控制系统

Model-Based Output-Feedback Network Control System

提出一种基于模型的输出反馈网络化控制系统。其主要思想是通过引入对象的输入输出模型和缓存器来克服网络造成的信息反馈不及时。该系统在不能获得反馈信息的时候,可以利用对象模型的输出值近似代替对象的输出值计算控制量,而在网络通畅时刻则利用对象输出计算控制量并刷新模型。给出了具体的算法,利用仿真示例验证了算法的有效性。

In this paper a class of output-feedback networked control systems is addressed.A key idea about this class of system is to introduce a plant model and a buffer to overcome the defect of feedback lag introduced by the network usage.When the feedback is unavailable,the control output is computed based on the plant model output,and when available,based on the plant output,meanwhile,the plant model is updated with the plant output.The concrete algorithm has been presented,and some simulations have been made to verify the algorithm.
