精密两维转镜作为激光角度欺骗干扰半实物仿真试验系统中模拟弹目、弹干扰视线运动的重要设备,其控制误差是影响视线运动模拟精度的重要因素,进而影响半实物仿真试验精度。以多体系统动力学方法推导了精密两维转镜的机电分析动力学模型,采用计算力矩法设计了两维转镜的轨迹跟踪控制器,并在Matlab/Simulink环境中对建立的反映转镜动态特性的数学模型进行了仿真,转镜方位、俯仰轴对等效正弦输入信号的角位置跟踪误差分别为2.2 mrad与3.5 mrad,结果表明:模型可实现对引导输入的角位置信号的高精度跟踪控制。
Precision two-dimensional rotating mirror as a laser angle deceptive interference semi-physical simulation test system to simulate the projectile, missile interference eye sight important equipment, the control error is an important factor affecting the accuracy of line of sight motion simulation, thereby affecting the accuracy of semi-physical simulation. Based on the multi-body system dynamics method, the electromechanical analysis dynamics model of the precision two-dimensional rotating mirror was deduced. The two-dimensional rotating mirror trajectory tracking controller was designed by the computational torque method. The built- The dynamic characteristics of the model are simulated. The angular position tracking errors of the equivalent sinusoidal input signals to the azimuth and pitch axes are 2.2 mrad and 3.5 mrad, respectively. The results show that the model can achieve high accuracy of the angular position signal, Tracking control.
