Finite-Time Tracking Control for a Class of MIMO Nonstrict-Feedback Nonlinear Systems Via Adaptive Fuzzy Method

This paper addresses the finite-time adaptive fuzzy control for multi-input and multi-output (MIMO) nonstrict-feedback nonlinear systems with fuzzy dead zones. Combining the semi-global practical finite-time stability criterion with the condition of variable partition, a feasible finite-time adaptive fuzzy control scheme is proposed for the developed MIMO system. The designed control algorithm guarantees that the tracking error converges to a small neighborhood of the origin in finite time. Compared with existing research results, the main advantage of this paper lies in that the finite-time control issue is considered for MIMO nonstrict-feedback systems with input nonlinearities. Two simulation examples are provided to illustrate the effectiveness of the suggested approach.
