摘　　要：飞行模拟器转台伺服系统是导弹飞行的重要模拟设备,用于获取实验数据;针对飞行模拟转台伺服系统在跟踪控制过程中存在参数不确定性、非线性摩擦等不确定性问题,提出了一种基于微分观测器的飞行模拟转台伺服系统非线性控制方法;考虑系统在跟踪控制过程中存在不确定性问题,设计了微分观测器来估计复合不确定扰动;设计非线性控制器来控制飞行模拟转台伺服系统,使得系统可以收敛到期望位置转角信号;通过李雅普洛夫稳定性证明控制器作用在系统条件下的鲁棒性;通过MATLAB/Simulink仿真试验平台验证了文中提出的控制策略能够使系统有效跟踪期望位置转角,具有一定工程应用价值。Flight simulator turntable servo system is an important simulation equipment for missile flight,which is used to obtain experimental data.A nonlinear control method of flight simulation turntable servo system based on differential observer is proposed to solve the problems of uncertaint parameters,nonlinear friction and other uncertainties in the tracking control process of the flight simulation turntable servo system;Considering the uncertainty of the system in the tracking control process,a differential observer is designed to estimate the composite uncertain disturbance;A nonlinear controller is designed to control the flight simulation turntable servo system,so that the system can converge to the desired position and angle signal;The robustness of the controller under the system conditions is proved by Lyapunov stability;Through MATLAB/Simulink simulation test platform,it is verified that the control strategy proposed in this paper can make the system effectively track the desired position angle,which has a certain engineering application value.
