Fuzzy variable structure control of dynamical systems with an application to micro satellite stabilization

Abstract

This paper is on determining a hybrid form of control which has both Fuzzy Logic Control (FLC) and Variable Structure Control (VSC) integrated. This proposed Fuzzy Variable Structure Control (FVSC) approach combines the power of approximate reasoning of FLC with the switching synthesis used in VSC. The FVSC is applied to control and stabilize a micro satellite in space. A model of satellite is used in this study in order to ensure the applications of FVSC in space. The simulation results indicate that the fuzzy logic can be advantageously used to minimize the chattering and improve the time response in the satellite system. MATLAB SIMULINK is extensively employed in this work.
