Abstract

The invention discloses an optimal linear control method for a network control system based on a distributed wireless network. The method analyzes the influence of time delay packet loss of the wireless network on the network control system for the long network time delay and the continuous packet loss characteristic of the distributed wireless network. The method adopts a quadric cost function as a system utility function and utilizes a method for iteration from back to front to obtain an optimal linear closed-loop state feedback control strategy for wireless network control, the quadric cost function is a linear function for the current state of a platform and a past control signal, and meanwhile, an optimal design scheme for a position of a control node network is provided. The method utilizes the distributed characteristic of the wireless network to select one node in the network as a controller flexibly and conveniently, and through selecting a proper network transmission path, the system stability of the wireless network control system can be effectively improved, and the system loss can be reduced.

Description

technical field

[0001] The present invention belongs to the field related to network control systems, in particular to an optimal linear control method for a network control system based on a distributed wireless network, and further relates to an optimal linear control method for a network control system based on a distributed wireless network with network delay and packet loss. Linear state closed-loop feedback control method. Background technique

[0002] The networked control system's analysis of control systems has changed from the concept of "system and control" to the category of "network and control", which has had a significant impact on the development of many research fields including communication principles and control theory. In the networked control system, the object of analysis is no longer an isolated control process, but the stability analysis, transmission characteristic analysis and scheduling management of the entire network control system including the...
