Adaptive Freely Hierarchical Variable Structure Control of Discrete Chaotic System

  • Discrete chaotic system was controlled to reach the given orbit xr by using the adaptive freely hierarchical variable structure control scheme. The adaptive control scheme was used when hierarchical sliding mode was close to the hyperplane in a small scope. The control intensity and control scope would be changed adaptively with the variation of the error between x(k) and xr by using the adaptive scheme. The largescale control intensity was avoided in the small control scope by using this control scheme. Any orbit in the output scope could be obtained accurately by using this control scheme. The output’s dithering was reduced effectively and the precision of controlling was enhanced by using this adaptive freely hierarchical variable structure control scheme.
