1摘要电机控制系统发展到现在，极为迅速而且较成熟。电动机也被广泛应用于工业中，成为工业越来越重要的一部分。电机控制系统也因其具有良好的性能，如结构简单、易操作、易控制及经济效益好等，被各高校和企业列为重点研究对象。在调速系统中，PWM 双闭环直流调速系统是优越性能比较好的系统，应用也非常广泛。在电机调速系统中，有着重要的地位。本文主要从双闭环直流调速系统的组成、调速方法、起动过程等作出分析，阐述该系统的优良性能。同时从转速、给定电压及电流等方面对电机系统的稳定性进行研究分析。其次，通过软件的作用，针对本次系统进行科学合理的仿真，从而获得后期的效果图，以进行相对深入的细致分析。通过仿真，分析调速过程与系统稳定性之间的联系。本文是借助 PWM 双闭环直流调速系统来分析电机系统的稳定性。关键词：稳定性；调速；双闭环；Simulink；直流电动机2abstractThe motor control system has developed rapidly and maturely up to now. Motor is also widely used in industry, becoming an increasingly important part of industry. Because of its good performance, such as simple structure, easy operation, easy control and good economic benefits, the motor control system has been listed as a key research object by universities and enterprises. In the speed control system, PWM double closed-loop DC speed control system has better superiority and wide application. In the motor speed control system, has an important position.This paper mainly analyses the composition, speed regulation method and starting process of the double closed-loop DC speed regulation system, and expounds the excellent performance of the system. At the same time, the stability of the motor system is studied and analyzed from the aspects of speed, given voltage and current. Finally, the system is simulated with the help of MATLAB/Simulink software, and the results are obtained and analyzed. Through simulation, the relationship between speed regulation process and system sta...
