一种BUCK电路自适应的滑模控制算法

针对常见的BUCK电路滑模控制方案中存在的负载突变产生的干扰问题,设计一种新的自适应滑模控制器.通过观测BUCK电路中负载电阻的变化,自适应的修改控制参数以获得良好的动态性能和稳定性.通过实验仿真证明该方法在负载电阻变化时,能有效减小系统状态误差和提高系统稳定性.

An Adaptive Sliding Mode Controller for Buck Converter

Against to the undesirable performance of usual sliding mode control schemes for buck convert due to the load variations,this paper proposes a new adaptive sliding mode controller for buck converter.Through monitor the output loading condition,the controller adaptively changes its control parameters to receive optimal dynamic performances.Finally,the result of simulation confirms that the adaptive control schemes are capable of reduced steady state error and improver controller's reliability during load var...
