摘　　要：飞行仿真转台是航空、航天领域中进行半实物仿真和测试的关键设备,是一个高精度的复杂系统,分析了飞行仿真转台伺服系统的数学模型,给出了系统控制结构图。滑模控制是一种非线性控制方法,对参数变化和扰动具有完全的自适应性,将离散滑模控制引入到转台伺服系统的控制中,给出了离散滑模控制器的实现过程,通过引入卡尔曼滤波器改善了系统的控制品质,软件仿真结果表明所设计的离散滑模控制器能达到较好的控制品质,有效的减小了系统抖振,提升了系统的抗干扰能力。Flight simulator turntable was a significant device in aviation and aerospace field for simulating,which was also a complicated high precision syste.First the mathematical model of the flight simulator servo system was analyzed and the control diagram was proposed.Since the sliding mode control was a nonlinear control method which was adaptive to disturbance and parameter variations ,the discrete sliding mode control combined with Kalman filter was introduced to enhance the control charaeter.The simulation shows the sliding mode controller with good control performance reduces chattering and enhances noise interference ability.
