摘要
开关变换器是一个非线性变结构系统,线性控制算法的控制性能在开关变换器系统中受到制约.针对这一问题提出滑模变结构控制法在开关变换器中的应用.滑模变结构控制法对被控系统数学模型精度要求不高,对系统参数变化、外界环境扰动具有完全的自适应性.以Buck型变换器为例,分析滑模控制在开关变换器中的使用方法,并给出了仿真和实验结果.
The DC-DC converters are nonlinear systems in nature,for which the performance of linear control methods is constrained.The sliding mode controller for DC-DC converters is presented.Sliding mode control（SMC） is widely used in practical applications due to its simplicity and robustness against parameter variations and disturbances.The Buck converter is used as an example to analyze the sliding mode controller applied in DC-DC converters and the simulation and experimentation results are presented.
