Missile Loading System Monitoring Software Design And Calibration Method

This paper studies the design of precept of missile's wing and rudder load simulation system whose core is digital signal processor(DSP) and DTC servo driver. Basing on the analysis about the reason that how the superabundant torque appears, direct torque control strategy is used to realize the servo control of two asynchronous motors and load system's simulation. The measure method of superabundant torque of the system, the valid method of static state torque and the benchmark of dynamic torque are given by testifying the system's speediness through experiments. On the basis of studying the principles of scheduler of real-time multitask, the design of the software of the load system is finished and the priority of different tasks is established. Different functions of the system including data input, dada storage, data communications and data display are realized on the platforms of C++ Builder and Paradox. The software designed for the system is validated by experiments and proved correct. The system can simulate the real air-stream and put it on missile's wings to make them work under the same force environment as the real spread process, so the relationship of explosive stuff and attack angle can be calculated.At present, most load systems in China are fluid drive systems; this paper solves two main difficulties 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.
