本文借助李雅普诺夫稳定理论研究了一类具有有界参数和扰动不确定性离散系统的滑动模控制方法，并将其用于一飞行仿真器的高精度伺服控制，得到了较好的仿真和实验结果． In this paper, by using Lyapunov stability theory, a sliding mode control method for a class of discrete systems with bounded parameters and disturbance uncertainties is studied and used for high precision servo control of a flight simulator. The simulation and Experimental results.
