| 摘 要： | 本文在分析DC／DC开关变换器滑模控制方法的基础上，针对以往开关变换器滑模控制器抖振现象严重的缺点，通过引入趋近律的方法，以Buck变换器为例，给出了一种适合PWM控制方式的时不变滑模控制器的设计方法。仿真结果表明，该控制方案可以减少系统超调，动、静态特性较好，并能有效削弱滑模运动的抖振现象。

| Abstract: | Considering the defects of ancient time-invariant method in shaking phenomena, taking Buck-type converter as example, a novel time-invariant sliding mode control techniques propitious to PWM control method, by quoting the approach law, is introduced in this paper. Simulation results show that time-invariant sliding mode controlled converter has characters with stability, robustness and good dynamic response at perturbation of supply and load. |
