摘要
由于 DC/ DC升压变换器的非线性以及由升压带来的非最小相位特性 ,使得其控制问题遇到了一定的挑战。为改善 DC/ DC升压变换器的控制性能 ,设计了一种非线性输出反馈控制器。该控制器仅采用系统输出信息作为反馈控制量 ,结构简单 ,易于实现。同时 ,该控制器具有良好的动态特性 ,并可使 DC/ DC升压变换器的平均系统指数稳定。通过对 DC/ DC升压变换器的仿真结果表明 。
Control of DC/DC boost converters is challenged due to their nonlinearities and non minimum phase property.In order to improve the control performance of DC/DC boost converters,a nonlinear output feedback controller is proposed.This controller is easy to implement since it needs system output information only and has simple structure.In addition,the said controller has excellent dynamic characteristics and can make the average system stable exponentially.Simulation results of a certain DC/DC boost converter indicate that the control solution presented above is feasible.
