Abstract

The invention discloses an asynchronous switching control system in a network environment, and relates to the technical field of control systems. The network is connected with a network distributor, the network distributor is connected with a controller, a plurality of subsystems of the controller are connected with a state feedback controller, the state feedback controller is connected with a continuous time network control switching system, the continuous time network control switching system is connected with the plurality of subsystems, and the subsystems are connected with equipment. Whenthe subsystems are switched, the index stability of the system is ensured through the corresponding controller, and a good transition curve is formed on a switching surface; accurate control can be achieved, stability is high, operation is easy and convenient, use is convenient, and time is saved.

Description

technical field [0001] The invention belongs to the technical field of control systems, and in particular relates to an asynchronous switching control system in a network environment. Background technique [0002] Network control system is a fully distributed, networked real-time feedback control system. Introduce the communication network into the control system, connect intelligent field devices and automation systems, realize the distribution and networking of field device control, and strengthen the connection between the field control layer and the upper decision-making layer. Since the sampling and control signals are transmitted through the network, the system will have problems such as network-induced delay, data packet loss and out-of-sequence. Among them, the network delay may be constant, time-varying, or even random. Contents of the invention [0003] In order to solve the existing sampling and control signal transmission through the network, the system will ...
