摘要: 基于负载反复切换的电机模型设计了参考模型自适应跟踪控制器.首先,构建电机的切换系统数学模型,并将负载更替看作切换信号.其次,对切换系统进行自适应控制器设计,解决了负载切换后出现的误差瞬增问题,保证了系统的渐进跟踪.最后,给出仿真算例,验证所设计控制器的性能,并说明了切换信号对系统动态特性造成的影响.

关键词: 跳变负载, 切换系统, 自适应控制, 跟踪

Abstract: An adaptive tracking controller is designd for motor with shifting load in this paper.First,amathematic model of motor switching system is built where shifting load is regarded as a switching signal.Then adaptive controller of switching system is designed,which solves the problem of tracking error that increases rapidly after load switching and ensures asymptotic tracking of the system.Finally,examples and computer simulation validate the performance of designed controller,and the impact of switching signal on system dynamic property is explained.

Key words: transition load, switched system, adaptive control, asymptotic tracking
