英文摘要: This research proposes a cooperative optimization scheme of distributed model predictive control based on cooperative theory, which is used in the general networked dynamical systems. First, a cooperative optimization control strategy and a distributed model predictive control strategy are combined to propose a cooperative optimization distributed model predictive control structure . In order to guarantee the stability of distributed model predictive control, topology-based cooperative Lyapunov function and the coupled relationship of networked dynamical subsystems will be considered. Second, the convex suboptimization is solved by decomposing systems and seeking the coupled relationship. Then, the relationship between global optimization and local optimization will be obtained. To achieve the method of the global system converging to a global optimization, we propose a cooperative control theorem, which is based on analyzing the subsystems' self-feedback control and the cooperative control of their neighbors. Finally, in the complex topographic environment, a multi-robotic cooperative optimization rescue system will approve the proposed cooperative control method for distributed model predictive control scheme.This research will promote the theoretical and practical development of cooperative control and distr
