The Control Analysis And Web Implementation Of Networked Control System

The control system of 21st century will be the combination of network and control theory, which is the focus of current research. Networked control system (NCS) reveals the development trend of the networked, integrated and distributed characteristic. Therefore, it is practical to make research in this field. With the development and maturity of networked control theory, networked cooperates with robot control gains more and more attention. This article mainly addresses the stability of NCS system and implements a web-based robot control platform.First, the robust H∞control of a class of networked control systems with uncertain delay is studied. Supposed that the controller and actuator of the network control system (NCS) are event driven, the sensor node is time driven, the network induced delay is time-varying, uncertain and less than the sampling period, the generalized plant is modeled as an uncertain linear discrete system. Based on Lyapunov function and linear matrix inequality (LMI), a sufficient condition for NCS which was subject to the asymptotic stability and the design approach of the controller was also given. The simulation verifies the proposed approach.Second, we bring forward another NCS model on the basis of last part, derive sufficient time-related condition for H∞controller presence in term of Lyapunov function and linear matrix inequality (LMI).The feasibility also is proven in this part.Last, we compare the traditional C/S model with B/S system construct model in this paper, gain the basic frame of remote control system on the basis of B/S model, and implement the web-based remote robot control system.
