This paper presents a finite-time adaptive fuzzy control scheme for MIMO nonstrict-feedback nonlinear systems with fuzzy dead zones, ensuring tracking error convergence to the origin in finite time. The main advantage is addressing finite-time control for MIMO systems with input nonlinearities, with simulation examples provided to demonstrate effectiveness.
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.
