【摘要】 介绍了滑模控制技术的基本概念。以Buck型变换器为例,对包括变频滑模控制技术和定频滑模控制技术在内的滑模控制技术作了综合论述。运用相平面法形象地描述了滑模运动,并采用映射法把三维轨迹化为两维情况,简化了分析过程。最后预测了滑模控制技术的发展趋势及今后研究的重点问题。更多还原

【Abstract】 The basic concept of sliding mode control was outlined first.And then an overview of sliding mode controller for Buck-kind converter was presented,included sliding mode control of both variable and fixed frequency.The sliding action was described by phase trajectory vividly.To simplify the analysis,three-dimension trajectory transforms into the two one through mapping method.Finally,the development trend and the point problem study from now on of sliding mode control were discussed.更多还原
