Abstract

The invention discloses a coordination control method based on the modeling of an actuator saturation multi-intelligent system and relates to the field of multi-intelligent systems. The method comprises the following steps of firstly, establishing an object subsystem mathematical model that meets the production scheduling requirements and the information flow rule constraints of the production process; secondly, establishing an information interaction network among all subsystems through statistical analysis, determining a leader system and a tracker system, and obtaining a self-adaptive coupling weight among network parameters and subsystems by utilizing relevant indexes; thirdly, respectively constructing a low-gain controller and a high-gain controller through solving out the feasible solutions of controllers; finally, applying low-high gain adaptive control laws to each subsystem to realize the tracking control of the leader system for the tracker system. According to the technical scheme of the invention, the obtained controller can be applied to various nonlinear dynamic systems and nonlinear input variables. Meanwhile, the method can also be directly applied to existing distributed control systems. Based on the method, the control cost is reduced, and the control precision is improved.

Description

technical field [0001] The invention relates to the field of multi-agent systems, in particular to a coordination control method based on actuator saturation multi-agent system modeling. Background technique [0002] In recent years, due to the fact that efficient plant-level control can perform distributed constraint optimization operations in industrial production processes, reduce energy and raw material consumption, and improve the production efficiency of industrial systems, it has attracted extensive attention from the industry. However, many objects in the process industry are often large-scale complex systems composed of subsystems or link units. According to the mechanism properties of energy or information flow, the production system of process industry can be modeled as a large number of subsystems based on network communication. Therefore, the coordinated control among subsystems becomes extremely important. [0003] According to its structure and networking, i...
