We proposed a new approach of the adaptive fuzzy control to solve the tracking problem of the MIMO NSPS with unknown models.The NSPS was decomposed into slow and fast subsystems.For the slow-subsystem a direct adaptive fuzzy controller with adjustable parameters was designed to make the slow variables follow desired trajectory.As for the fast-subsystem a fuzzy controller was used to guarantee the fast variables stable.The whole controller was the composition of the slow and fast control.Lyapunov synthesis approach could guarantee the stability of the whole system provided that the perturbation parameter is small enough.Simulations illustrate the effectiveness of the proposed approach.
