基于LPC2292数字自整角机转换控制的研究

摘要

Introducing how to use Micro Processor LPC2292 and AD7537 as its key parts to generate two sine and cosine functions,and using Scott transformer to achieve the transforming method of from digital signal to synchro signal,how to use the control method of many steps to control the velocity of synchro is analyzed.After the experimental proof,using this method in the digital signal drives synchro interface system of autopilot steering,its performances can meet the requirements.%介绍了如何用以微处理器LPC2292和AD7537为核心部件产生两个正、余弦函数,同时利用斯柯特变压器实现数字信号到自整角机信号的转换,分析了如何采用分段控制方法来对自整角机的速度进行控制。实验结果表明,在自动操舵仪数字信号驱动自整角机的接口系统中采用该方法其性能可满足要求。
