| Abstract: | 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. |
