Abstract: For integrated-electro-hydraulic brake system,a method of actuator parameters optimization for response performance was proposed.Combined with the structure of actuator,the parameters were preliminary matched.Based on the state equation of integrated-electro-hydraulic brake system,the motor angular displacement was taken as the control variable to establish the hydraulic response performance simulation model of the motor angular displacement.Following the proposed simulation model,the effect of actuator parameters on response performance of angular displacement was analyzed.An optimization model that took steady state error and rising time of the motor angular displacement response performance as the optimization objectives was built,which was solved by the simulated annealing particle swarm algorithm.The optimization results showed that the optimized parameters of actuator could improve the response performance of electro-hydraulic brake system.
