Research of Hardware-in-the-Loop Simulation Based on RT-LAB

Hardware-in the loop simulation plays a very important role in missile design. Simulation can test the performance and harmony of each part of the missile at minimum cost. This paper presents the development method and programming essentials of PCI card driver under QNX based on simulation of X-type IR seeker. Some problems that may be encountered in the process are described in detail. The paper also presents a guide to RT LAB and how to design the simulation model. The research shows that RT-LAB can apply Simulink model in hardware-in-theqoop simulation system conveniently and rapidly. The system takes QNX as the target node and improves stability, reliability and the real time performance of the simulation. The result indicates that the simulation system is stable and reliable in simulation of X-type IR seeker.
