根据某型红外空空导弹发射装置离轴控制系统的测试需求,针对已有测试设备模拟电路调试复杂、排故困难以及不能模拟导弹位标器实时随动目标的问题。通过对导弹离轴控制回路工作过程及阀控制算法的分析,文中提出了一种基于DSP的设计方法,运用基本的数、模集成电路,结合软件编程,简化了原有测试设备的离轴控制电路,并实现了模拟位标器实时随动目标的功能。其正确性已在产品上得到了充分验证。

According to the test needs of the off-axis control system of the IR air-to-air missile launcher, aiming at the problems that the previous testing equipment failed to simulate the seeker following targets in real-time, and the analog circuits with complex debug and difficult check-up. By analyzing the working process of the missile's off-axis control loop and the control algorithm of valves, the paper proposed the design basis on DSP, using the basic digital and analog integrated circuits, and software programming, which simplified the off-axis control circuit of the previous testing equipment, and implemented the function of simulating the seeker following targets in real-time. Its correctness is fully validated in the products.
