直流电机晶闸管调速系统的设计与分析
摘要
运动控制系统中应用最普遍的是自动调速系统。自动调速系统主要包括直流调速系统和交流调速系统。在高性能的拖动技术领域中,相当长时间内基本采用直流电力拖动系统。直流调速是指人为地或自动地改变直流电动机的转速,已满足工作机械的要求。从机械特性上看就是通过改变电动机的参数或外加电压等方法来改变电动机的机械特性,从而改变电动机机械特性和负载机械特性的的交点,使电动机的稳定运转速度发生变化。
本文以直流电动机为对象,先是分析晶闸管电动机调速系统的开环工作机械特性,然后分析单闭环有静差和无静差工作的系统静特性,以及着重对转速、电流双闭环的机械特性设计与分析,并应用MATLAB软件对系统模型进行了仿真研究。

The design and analysis of Thyristor DC motor speed control system
ABSTRACT
Application in motion control system is the mon form of automatic speed control system. Automatic speed control system includes AC variable speed DC drive system and the system. Drag in the high-performance technology, the relatively long period of time almost all the DC electric drive system. In addition, based on feedback control theory based on the principle of DC Speed Control Speed Control is the basis of the exchange. DC converter is artificially or automatically change the speed of DC motor has to satisfy the requirements of mechanical work. Judging from the mechanical characteristics of the motor is by changing the applied voltage and other parameters or methods to change the motor's mechanical properties, thereby changing the motor characteristic and load mechanical characteristics of the intersection, the stable operation of the motor speed change.
This paper focuses on the SCR motor speed control system of open-loop mechanical properties of the work, single loop with static error and poor working system with no static static properties, mechanical properties and the double closed-loop system closed-loop control characteristics were tested. And apply the MATLAB software system model was simulated.
Keywords: DC motor speed; thyristor;open loop; double loop; MATLAB simulation
