| 摘 要： | 应用状态轨迹预测的方法,调节Buck-Boost变换器电压输出。根据在一个假定的开关动作后预测电压输出,设计二阶开关面,在一个开关周期内就可引导系统轨迹到达目标工作点,具有大信号稳定性,对负载扰动及电源扰动均有很强的自适应性,通过仿真验证了理论的正确性。

| Abstract: | State trajectory prediction is applied to regulate the output voltage of buck-boost converters.A second-order switching surface is designed based on the predictingthe output voltage after a hypothesized switching actions,o the output system can reach the target operating point in one switching cycle.The proposed method,with the characteristics of fast dynamic responses,imple stability criteriaa,nd strong robustness against input disturbances and output load disturbances,is suitable for large-signal analysis,and can be applied to other nonlinear power converters. |
