Real-time on-line control system and method for miscellaneous nonlinear system

Abstract

The invention provides a real-time on-line control method for a miscellaneous nonlinear system. The method is characterized by comprising the following steps of: a, transmitting the current observation state information of a network controlled object to a first controller, wherein the first controller is used for providing real-time on-line control for the network controlled object to make the network controlled object asymptotically stabilized; b, acquiring control output quantity information at the current moment by using the first controller according to the current observation state information; and c, feeding the control output quantity information back to the network controlled object, wherein the network controlled object is the miscellaneous nonlinear system. The aim of asymptotically stabilizing the network controlled object by controlling the miscellaneous nonlinear system through a network is fulfilled by a method for controlling a quantization controller. Particularly, observation information is quantized and then is transmitted, so that the load of the network is lightened.

Description

technical field [0001] The invention relates to a network control system, especially to a control method of the network control system, in particular to a real-time online control method for a hybrid nonlinear system. Background technique [0002] With the rapid development and cross penetration of computer technology, network technology and communication technology, the structure of modern control systems is changing, and more and more control systems adopt distributed control. The control tasks transmitted through wired or wireless communication lines are called Networked Control Systems (NCSs). NCSs is the product of cross-integration of control, computer, communication, network and other technologies. It is an objective requirement for complex large-scale system control and remote control. It can be applied to almost any occasion where distributed equipment with a controller needs to exchange data. It reflects the development trend of the control system towards networki...

AI Technical Summary

Problems solved by technology

[0003] Due to the introduction of the communication network in NCSs, and limited by the limited network communication bandwidth, carrying capacity and service capacity, many devices connected to the network have to send information, and the transmission of information needs to occupy the network communication line in time, which will inevitably lead to the loss of information. Congestion, collision, retransmission and other phenomena occur, which inevitably brings many challenging new problems in the process of information transmission: uncertain network time delay, data packet loss, multi-packet transmission, jitter, clock asynchrony, etc.

However, the disadvantages of the prior art with the above content as an example are that these technical solutions for designing network control systems are all based on the complete transmission of network signals and can be completely obtained, and do not consider the signal in the network. Transmission due to factors such as loss of effective information that may be caused by limited network bandwidth

So far, there are few studies on the modeling, quantitative control problem of nonlinear time-delay hybrid NCSs
