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.

本文讨论了具有模糊盲区的多输入多输出 (MIMO) 非严格反馈非线性系统的有限时间自适应模糊控制。结合半全局实用的有限时间稳定性判据和可变分区条件，提出了一种可行的有限时间自适应模糊控制方案，适用于所开发的MIMO系统。设计的控制算法保证跟踪误差在有限时间内收敛到原点的一个小邻域。与现有研究成果相比，本文的主要优点在于考虑了输入非线性的 MIMO 非严格反馈系统的有限时间控制问题。提供了两个仿真示例来说明所建议方法的有效性。
