【Abstract】 An algorithm of constrained state feedback model predictive control was proposed based on the chaotic particle-swarm optimization (CPSO) to solve the control problem with simultaneous constraints on inputs and states.CPSO was used for iterative optimization to enhance the capabilities of total search and partial search in the constraint area.A practical constrained optimization problem of the discrete-time linear system is solved by CPSO.The results show the feasibility and effectiveness of constrained state feedback model predictive control based on the chaotic particle-swarm optimization(CPSO).By comparing the simulation results of QP and PSO,we show the advantages of the PSO-based constrained state feedback model predictive control.The superior robustness of state feedback model predictive was also verified.更多还原
