For a class of Multi-Input/Multi-Output (MIMO) nonlinear systems with uncertainties and disturbances,this thesis proposes a asliding mode control (SMC) to improve the chattering phenomenon. First, an interval type-2 fuzzy logic system is used to estimate the upper bound of the unknown functions. Secondly, we replace the sign function by using an adaptive proportional integral (PI) term to reduce the effect of the chattering phenomenon. Finally, based on the Lyapunov stability, we design the adaptive tracking control law and verify the feasibility by applying the control law them to the mass-spring-damper system.
