【摘要】 本文研究了以数字信号处理器(DSP)和直接转矩控制器为核心的弹用负载模拟加载系统方案设计。在具体分析加载系统中多余力产生原因的基础上，采用直接转矩控制策略，实现了两台异步电动机伺服控制和加载系统的负载模拟实验，通过实验验证了系统的快速性；给出了系统多余转动惯量的测量、静态转矩的校验和动态转矩基准的实验的基本方案。在研究了实时多任务的调度原理的基础上，完成了整个加载控制系统的控制台计算机监控软件设计；制定了系统监控软件中各种任务的优先级，利用C++ Builder、Paradox等工具实现了系统的监控软件的各项功能，包括数据录入、数据存储、数据通信和数据显示等。本文所设计的监控软件已通过实际系统的验证，说明整个系统的设计是合理正确的，能够真实的模拟力矩，产生一种类似真实气流阻力的载荷，并将其正确施加于弹翼(尾翼)上，使弹翼(尾翼)能在与展开过程中实际受力相同的状态下工作。 国内现有的加载系统多为液压加载，本文的研究工作解决了电动加载的两个主要难点：快速性的实现和多余力的消除，对加载系统的研究有一定的参考价值。更多还原

【Abstract】 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.更多还原
