Abstract

An error sequence cognition based design method for an integrated controller of a network control system relates to the design technology for network control system controllers, and includes the following steps: a real-time statistical analysis based error sequence cognition method, an error sequence cognition based sampling rate adaptive algorithm, designing of a controller for integrally controlling the sampling rate and a controlled object, modeling of a network-oriented closed network control system, and stabilization analyzing and performance optimizing of a network-oriented control system. The method takes the error sequence cognition as the essential basis, takes the integral control as the basic mode, takes designing of the control law adaptive control sampling period and the controlled object as the basic measure, aims to obtain the key design technology of the integrated controller, and not only provides a new control method for solving the problem about the error sequence of the network control system, and provides technical supports for the network and control integrated design, but also has practical significances in realizing the highly reliable and hard real-time network communication, improving the application system performance, and lowering the energy consumption.
