The problem of nonlinear system stable control had been studied. Nonlinear system was described based on HM (homogeneous model) model.The globle HM model was translated into system with uncertainty. Under the situation that the uncertainty satified match condition, Lyapunov stable theory was used to design sliding mode variable controller, in order to ensure the global asymptoticlly stability of the system. The simulation of an inverted pendulum showed that the structure of the controller was simple, and the effect of the control was satisfied only with less fuzzy rules. Succeed in using variable structure control into nonlinear system, it is worth being extended.
