摘　　要：介绍了采用CPLD器件开发的导弹用惯性测量单元(IMU)模拟器的设计原理及其实现方法。该模拟器采用软硬件相结合的方式,可模拟某型真实惯性测量单元(IMU)的接口与输出信号。通过软件控制硬件输出的脉冲个数,可模拟真实惯性测量单元在静态和动态工作时的状态。该模拟器具有硬件体积小、成本低、可连续长时使用等特点和可轻松修改模拟器硬件电路的优点。该模拟器在某型号空空导弹惯导系统仿真实验中已经得到实际应用。The paper introduced the design principles and implementation method for missile inertial measurement unit simulator based on CPLD. The simulator adopted the way of combining hardware with software, which could simulate the interface and output signals of a certain real inertial measurement unit. By using the software to control the number of impulse of hardware output signals, it could simulate the operation of a certain real IMU, including static state and dynamic state. The simulator has the characteristic of small hardware volume, low cost and long-time continuous operation, and its hardware circuit can be easy to modify. The simulator has been used in the simulation of a certain air-to-air missile inertial navigation system.
