A New Simulation Technology Research for Missile Control System based on DSP

Abstract. Simulation technology is extremely important in the design process of control algorithm for missile weapon system. Different from digital simulation and traditional hardware-in-the-loop simulation, a rapid prototyping hardware-in-the-loop simulation technology is proposed which can confirm the control algorithm by implementing a prototype of the control system in the loop, making the simulation more reliable and effective. In the simulation process, a high-end computer as the HOST PC simulate the external physical environment and the internal physical characteristics of the missile while the control system running on a prototype DSP controller makes response to the real signals and gives real output. Through serial communication a high-speed real-time data exchange channel is built to complete the interaction of sensors and control commands. Simulation results for a certain type of missile weapon system show the rapid prototyping hardware-in-the-loop simulation technology is effective
