摘　　要：变结构控制对系统参数的变化和外部干扰具有理论上的完全鲁棒性,然而,实际系统中在滑模面上的抖振问题却是其工程应用的主要障碍。研究了变结构控制的基本原理和产生抖振的原因,总结出了多种削弱抖振的方法。指出组合控制方法得益于先进控制理论和应用技术的发展,是处理抖振问题的发展方向。For the changes of system parameters and external interference variable structure control is completely robustious in theory, however, chattering problems on the sliding surface of an actual system are main obstacles in its engineering applications. Studies were made for the basic principle and causes of accurat of chattering for variable structure. Summarizing many methods to weaken the chattering, and pointing out that composition control method which benifited from advanced control theory and application technology development is the development direction of chattering problem disposal.
