Electric Loading System. Dsp-based Bomb

This paper studies the design and the realization of missile's wing and rudder load simulation system which core are digital signal processor (DSP) and DSC servo driver.On the base of significantly study, the control strategy, the reason of the superabundant torque and the method of elimination of the superabundant torque was analyzed and discussed. The system designed is composed of the same driver system and two asynchronous motors, which buildup a servo system with good performance. The paper gives the details about system's precept, control current, parts selection, hardware and software debugging, analyzing and calculating. The work of system's efficacy and design of system's reliability are finished.The load control system has already passed the test's validate. It shows that the design of whole system is correct. The system can truly simulate the real air-stream and put it on missile's wings to make them work on the same force situation as in the real spread process, so the relationship of explosive stuff and attack angle can be confirmed.At present, the moment to load missile's wings and rudders is relied on fluid driver framework, the paper solves two main problems in electro-motion system: the realization of speediness and the elimination of the superabundant torque. It can provide some new information in load system's further investigation.
