摘　　要：针对煤炭矿山领域特定的工况,以及位置传感器会降低系统可靠性、增加成本等问题,将滑模观测器(SMO)引入无刷直流电机(BLDCM)无传感器控制系统中。针对滑模控制的抖振问题,引入一种新型的滑模趋近律,构建新型SMO,通过数学公式推导分析其在抖振抑制和快速响应等方面的优势,并基于此设计一套BLDCM的双闭环控制系统。最后,通过仿真和试验验证所提基于滑模控制器的BLDCM控制系统的性能。结果证明,基于新型SMO的BLDCM无传感器控制系统运行性能良好,能够完成BLDCM状态量采集、位置判断等功能。Aiming at the specific working conditions,and the reliability reduction and increase in cost by the location sensors in the coal mine area,the sliding mode observer(SMO)was introduced into the brushless DC motor(BLDCM)sensorless control system. In view of the serious buffeting problem of the sliding mode control method,the principle of sliding mode control was introduced,a new sliding mode reaching law was introduced to build a new sliding mode observer,its advantages in anti-interference and rapid corresponding were analyzed through mathematical formula deduction,and a double closed loop control system of BLDCM was designed. Finally,the performance of the BLDCM control system based on sliding mode controller was verified by simulation and test. The results show that the BLDCM sensorless control system based on the new sliding mode observer is good in running performance,and can accomplish BLDCM status acquisition,location estimation and so on.
