A hybrid fuzzy self-organizing variable structure controller

الملخص EN

In this paper the problem of chattering in variable structure controllers is addressed.

A new performance index for chattering developed by the authors is used in a Hybrid Scheme employing both adaptive and fuzzy logic schemes to smooth out the chattering phenomenon and simultaneously increase the speed of the system response.

Simulations are carried out for single input multi output and multi input multi output systems.

The simulation results show that the proposed Hybrid Fuzzy scheme is very effective in reducing both magnitude of the control and chattering phenomenon without compromising speed of response of the systems.
