Coordination control method based on modeling of actuator saturation multi-intelligent system

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.
