摘要: 针对周视光电观瞄系统中机械传动装置实现光学消像旋的情况，分析了传统光学消像旋的利弊。通过简化机械装置，建立了控制对象的数学模型，根据系统实时控制处理的要求，设计了数字控制和模拟控制的混合电路，提高了系统的稳定性和可靠性。运用MATLAB/SIMULINK对控制系统的典型情况进行仿真。仿真结果表明，该电路系统都能满足精度和实时性等指标要求。Abstract: Based on the optical image de-rotation implemented by the transmission mechanism of a panoramic observation sight, the advantages and weaknesses of traditional optical de-rotation methods were analyzed. By simplifying the mechanism, the mathematical model of the controlled object was established. According to the system requirements of real-time controlling and processing, the digital-analog control hybrid circuits were designed, which improved the stability and reliability of the system. A typical instance of the control system was simulated with MATLAB/SIMULINK, the results show that the electric circuit can meet the requirements of stability and real-time processing.
