摘要调速系统是当今电力拖动自动控制系统中应用最广泛的一种系统。目前对调速性能要求较高的各类生产机械大多采用直流传动，简称为直流调速。从上世纪50年代末开始，晶闸管出现，且晶闸管变流技术日益成熟，使直流调速系统更加完善。晶闸管－电动机调速系统已经成为当今主要的直流调速系统，特别是大型电机项目，广泛应用于世界各国。直流双闭环调速系统具有调速范围广、精度高、动态性能好和易于控制等优点，所以在电气传动系统中得到了广泛的应用。直流双闭环调速系统中设置了两个调节器, 即转速调节器(ASR)和电流调节器(ACR), 分别调节转速和电流。本文对直流双闭环调速系统的设计进行了分析，对直流双闭环调速系统的原理进行了一些说明，介绍了其主电路、检测电路的设计，详细介绍了电流调节器和转速调节器的设计以及一些参数的选择和计算，使其满足工程设计参数指标。关键词： ASR ACR 电机调速AbstractSpeed ??electric drive system is the automatic control system of the most widely used system . Current speed high performance requirements of various types of production machinery they use a DC drive , referred to as DC converter . From the late 1950s , the thyristor appears and thyristor technology matures, the DC speed control system more perfect. Thyristor - motor speed control system has become the main DC speed control system , especially for large motor project , widely used in the world.DC double loop speed control system, which has been widely used inthe electrical transmission system,has a great amount of advantages including wide speed range, high accuracy, good dynamic performance and ease of control.Double Closed Loop DC Speed Control System sets up two regulators, automatic speed regulator(ASR) and automatic current regulator(ACR), which adjust the speed and current, respectively. This article analyses the design of DC double loop speed control system, describes a number of principles of the system and introduces the design of its main and detection circuit. And then the article lists some details of the design of current regulator and speed regulator and tells how to choose parameters and calculation , making it meet the indicators of the design parameters.Keywords：ASR ACR motor speed control电机及其运动控制系统课程设计1摘要2一、原理介绍51、双闭环V-M调速系统整体工作原理52、系统各环节原理62.1 ASR极其限幅电路62.2 ACR及其限幅电路72.3 检测电路原理82.4 电机控制电路原理92.5 保护电路原理12二、系统设计、参数计算及仿真131、系统设计及参数计算131.1 设计对象131.2系统设计原则141.3系统设计步骤142、仿真212.1 基本仿真212.2 综合性能指标要求优化系统232.3 双闭环调速系统其它性能的研究仿真24三、心得收获25参考文献26一、原理介绍1、双闭环V-M调速系统整体
