摘要
针对滑模变结构的"通病"——抖振展开分析和研究,利用数学分析和离散控制相关理论对趋近律进行分析和整合,发现滑模变结构抖振在不同的控制系统中有相似的控制结果。在离散系统中,变结构表现出很好的控制效果和鲁棒性,主要是因为对干扰不敏感,对扰动有很好的过滤效果。最后对变结构控制的应用进行了展望。
The paper is based on analysis and research on chattering,which is the common problem in sliding variable structure.It analyzes and integrates the reaching law by using the theory of mathermatical anlysis and discrete control.The sliding mode chattering in different control systems has similar control results.In a discrete system,variable structure shows very good control effect and robustness because it is not sensitive to intereference and it also has good filtering effect on disturbance.Finally,the application of variable structure control was prospected.
