Abstract

The invention relates to a method for compensating the uncertain time delay of a double-input-output network decoupling control system, belongs to the technical field of multi-input-output network decoupling control systems with limited bandwidth resources, and aims to solve the problems that the double-input-output signals of TITO-NDCS affect each other and are coupled and need to be decoupled, the time delay generated during network data transmission among nodes affects the stability of each closed-loop control loop and the stability of the whole system, and even TITO-NDCS instability is caused. The method which uses the network data transmission process among all real nodes in the TITO-NDCS to replace network time delay compensation models among the nodes has the advantages that measuring, estimation or identification of the network time delay among the nodes can be avoided, clock signal synchronization requirements are lowered, influence of the uncertain network time delay on TITO-NDCS stability is lowered, and system control performance quality is improved.

Description

technical field

[0001] The present invention relates to automatic control technology, the intersection field of network communication technology and computer technology, especially relates to the technical field of multiple-input multiple-output network decoupling control system with limited bandwidth resources. Background technique

[0002] The closed-loop feedback control system composed of real-time communication network is called networked control system (Networked control systems, NCS). The typical structure of NCS is as follows: figure 1 shown.

[0003] In NCS, due to the introduction of the network, the complexity and cost of the control system are reduced, and many remote nodes (or devices) are organically combined through the network to cooperate to complete the work that a single node (or device) cannot complete. In addition, the information from different nodes can be integrated through the network to estimate, analyze and monitor the status of the network system...
