摘 要: 由于Boost变换器是一个非线性时变系统,使得控制器的设计遇到了一定的挑战。为改善Boost变换器的控制性能,本文设计了一种基于协同控制理论的控制器,并利用遗传算法对控制器参数进行优化。仿真和试验结果表明,该控制方法具有较好的启动特性,并对系统参数及负载的变化具有很强的鲁棒性。 Since Boost converter is a nonlinear time-varying system, its controller design is a challenging task.To improve the control performance of Boost converter,a controller based on synergetic control theory is designed.The parameters of the controller are optimized by a genetic algorithm.Simulative and experimental results of the certain Boost converter show the system achieves better start-up response and has strong robustness against the variations of system parameters and load.
