Missile Electric Load Control System Design And Realization

This paper studies the design and the realization of missile's wing and rudder load simulation system based on DSP (Digital Signal Processor) and DTC(Direct Torque Control) servo driver after introducing the basic principles of electric loading system .On the base of significantly study, the control strategy, the reason of the plus torque and the method of elimination of the plus torque was analyzed and discussed in detail. In hardware design, this paper introduces the hardware circuits based on DSP TMS320F2812 in detail. And the reliability and antijamming measures of the hardware is explained too. In software design, first the paper discusses the integrated software development environment for Texa Instrument's TMS320C2xx DSP. Then, connected with this system, it introduces each modules of the software, and prognosticate algorithm, table searching algorithm, and other core algorithms of the software. And the bidirectional communications between the computer and load controler is also included. At last, the reliability and antijamming measures of the software is discussed briefly. When the design and debugging of the whole system are completed, the results of a series of experiments are analyzed, and the conclusion is given.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 electric loading system: the realization of speediness and the elimination of the plus torque. It can provide some new information in load system's further investigation.
