摘要
本文采用离散滑模变结构控制方案，提出了一种新型PI调节器设计方案，给出了离散滑模变结构PI调节器滑模存在条件及调节器设计方案。理论分析和仿真结果表明，该调节器使对象具有良好的鲁棒性和性能指标，能消除持续恒定干扰造成的静态偏差。控制器输出切换极小，为快速的运动控制提供了一种新方案。
Based on sliding mode variable structure control theory of discrete system, this paper presents a new sliding mode variable structure PI regulator. The existence condition of the sliding mode and the design method of the regulator are given in the paper. The presented regulator has the advantages of both discrete sliding mode control and PI regulation. Theoretical analysis and simulation results show that the regulator is possessed of good robustness and control performance.
