Abstract:Because of the unstable manifolds near the inverted equilibrium, for the attitude control problems at the inverted
equilibrium position, T-S fuzzy model of the 3D rigid pendulum is modeled. Then by using the method of parallel distributed
compensation(PDC) and linear matrix inequalities(LMI), the stability analysis of closed-loop T-S fuzzy control systems is
investigated. The simulation results show that the T-S fuzzy control technique is feasible and effective.
