摘要

基于有限时间稳定理论和Lyapunov稳定性理论，设计一个非线性控制器，对无刷直流电动机（BLDCM）系统的混沌振荡进行控制。首先理论上证明了该控制策略能使混沌系统在有限时间内稳定到平衡点，然后利用数值仿真结果验证了该控制策略的正确性和有效性。研究结果对保证无刷直流电动机的稳定运行具有重要意义。

Abstract

In this paper, a nonlinear controller is designed to control chaos in BLDCM system based on finite-time stability and Lyapunov stability theory. Theoretical analysis proved that the control strategy can stabilize the chaotic system at the equilibrium point in a finite time. The numerical simulation results demonstrate the correctness and effectiveness of the proposed control strategy. The control strategy may have important implications for the stability operation of BLDCM in industrial automation manufacturing.

Keywords: finite-time stability theory, Lyapunov stability theory, chaos control, Brushless DC motor (BLDCM)
