摘要:
为了得到Boost变换器在负载和输入电压扰动下稳定的输出电压,针对Boost变换器的混杂动态系统特性提出了一种新的控制算法.首先根据混合动态系统理论建立变换器的混杂自动机模型,从而将控制算法的设计问题转换为混杂自动机切换条件的选取.然后通过对电感电流连续模式及电感电流断续模式工作过程的分析,采用电路理论法计算得到切换条件.最后采用MATLAB的Simulink和Stateflow工具箱对控制算法进行了仿真.结果表明设计的控制算法可以实现Boost变换器全范围的稳定运行,同时对负载和输入电压扰动都有很好的抑制效果.
Abstract:
To get a stable output voltage of boost converter under load and input voltage disturbances, a new control algorithm based on the hybrid features of boost converter was designed. Firstly, an exact hybrid automation model was built based on hybrid dynamic systems theory, and the problem of control algorithm design was equivalent to the guard-selection problem of hybrid automation. Then, the current flowing process was analyzed both in the continuous inductor current mode and in the discontinuous inductor current mode. The guard conditions were based on a circuit theoretical approach. Finally, the hybrid control algorithm was implemented by using simulink platform and the state flow chart feature of Matlab. The simulation results indicate that the boost converter can run under full operating ranges and has inhibitory effects on both load and input voltage disturbances by the proposed hybrid control algorithm.
