The Design and Implementation of Real-time HILS Based on RTX Platform

摘要：

Hardware in the Loop Simulation(HILS) plays an increasingly important role in the development and test system of missile. This paper describes the structure and function of a typical HILS Platform for missile testing. The platform has a double computers structure, which consists of the control computer and the simulation computer. The paper analyses the hardware and software requirements and gives the simulation workflow chart. Accuracy of the timer is one of the key techniques in the hardware in the loop simulation. Because of the poor real-time performance of Windows system, RTX HAL extension Subsystem is introduced to meet the real-time requirement of the system. This paper also studies the realization of accurate clock in the RTX, introduces the general process of driver development. The results of simulation experiments indicate that the platform has good real-time performance and runs stably and reliably. The flight data do not miss or mismatch in the whole simulation process. The platform fully satisfies the real-time requirements of hardware in the loop simulation for missile guidance and control system.
