摘要
针对移动目标模拟器负载转动惯量大、运动速度快、运动轨迹非线性的特点,以减小移动目标模拟器轮廓误差为研究目标,对移动目标模拟器伺服控制系统进行设计,建立移动目标模拟器伺服控制系统模型,将交叉耦合控制系统(cross-coupled control,CCC)引入伺服控制系统中,并在MATLAB中进行了仿真验证。仿真结果证明基于交叉耦合控制的移动目标模拟器比传统的基于PID控制的移动目标模拟器能达到更高的控制精度,使得模拟器能更加真实再现目标运动轨迹。
For the character of the high moment of inertia, high movement speed and high precision of the moving target simulator, with servo system as the research object, considering the factor of high moment of inertia, with the research focus of fast running system, output of actuator strictly following reference input of control system, and reducing contour error, the servo system is designed. The control model of moving target simulator servo system is built. The cross-coupling control system is introduced into the moving target simulator servo control system and the servo system is verified by using MATLAB simulation.
