摘要
建立电机泵复合控制功率电传作动系统非线性模型,采用粒子群优化算法,在保证允许的超调量的条件下,研究了电机、泵之间的权值最优分配,提高了战斗机的机动性能。并运用M atlab来求取非线性系统阶跃响应的调节时间。仿真结果表明,粒子群优化算法具有调节参数少、运行速度快等优点,能有效解决组合优化问题。协调控制器的研究对未来机载作动系统的控制具有指导意义。
A nonlinear model of electromotor - pump compound control power by wire （PBW） actuation system was built. To study the gain optimization distribution between electromotor and pump, particle swarm optimization （PSO） algorithm was implemented in the restriction of overshoot. Tactical aircraft maneuverability was enhanced. The method that solving the nonlinear function to get step response adjustment time with Matlab was proposed. The simulation results demonstrate that particle swarm optimization algorithm has the advantages of small tune parameter numbers and short running time. It works effective in combined optimization. The research on coordination controller will instruct for the control airborne actuation system in the future.
