摘要
针对传统控制方法不易取得良好的控制效果这一问题,为提升其性能,以滑模变结构方法为基础,基于DC-DC变换器系统,设计了DC-DC变换控制器。该控制器具备PWM调制、模糊逻辑控制和滑模变结构控制三者的优点,较好地解决了滑动模态的抖动问题。Matlab仿真结果证明了其可行性以及良好的动静态性能和较强的鲁棒性。
The traditional control methods are difficult to obtain good control effects for it,in order to enhance its performance,with sliding mode variable structural method as foundation,the DC-DC conversion controller has been designed based on DC-DC converter system.The controller provides all the advantages from PWM modulation,fuzzy logical control and sliding mode variable structural control,and solves the chattering problem better.The result of Matlab simulation proves that it is feasible,and excellent in static and dynamic performance and offers good robustness.
