| Abstract: | The nonlinear system is described based on HM model. The global fuzzy model has been translated into the system with uncertainties. The upper bound of uncertainties is assessed by adaptive method. Lyapunov method is used to design variable structure controller, in order to ensure the global asymptotically stability of the system. The method has been tested by simulation of an inverted pendulum and results in using variable structure control to nonlinear system, successfully. |
