摘要
介绍了非线性变结构控制系统的基本原理,论述了二阶阻尼系统的离散变结构的处理方法。着重分析研究了伪滑动模态产生的必要和充分条件及使用的范围。最后通过数字仿真结果,验证了伪滑动模态离散变结构控制系统的正确性和可行性。
Variable structure systems with sliding modes have been widely discussed and used in many different fields of applications. The precise behaviour at a switching surface is complicated because there the system is non-analytic. The damped simple harmonic oscillator with a nonlinear variable structure is discretised and analysed in detail, revealing the occurrence and structure of pseudo-sliding modes which give an insight into the corresponding sliding modes for the continuous system. Necessary and sufficient conditions are obtained and the analysis is illustrated with graphs form numerical solutions.
