中文摘要：
针对于无刷直流电动机混沌系统,考虑其模型不确定性及外界干扰项的存在,通过设计一种同步增广系统及其比例积分型滑模面,推导出一种自适应滑模控制策略,将无刷直流电动机混沌系统运行轨线控制至其平衡点的预定目标;为了进一步改善控制器品质,提出一种无抖振的滑模变结构控制,通过改进趋近律和控制器结构,消除了滑模变结构控制的抖振现象。
英文摘要：
The problem of controlling BLDC Motor uncertain chaotic system,exposed to external disturbances,was considered.An synchronous augmented system and its proportion integral type sliding surface were designed,and an adaptive sliding mode variable structure control strategy was deduced to drive the BLDCM chaotic system to the intended target.In order to eliminate chattering and improve control quality,an new sliding mode without chattering was proposed.The chattering of the sliding mode control was eliminated by improving the reaching law and building a new control system.
