摘　　要：介绍一种非独立的、可弱磁升速的直流电动机调速系统,并采用工程设计方法选定了励磁电流控制器和反电势控制器的参数,在MATLAB/SIMULINK环境下仿真得到该系统的控制效果。研究了突加、突减负载以及带恒功率负载时的系统响应。In this paper, a kind of DC motor speed regulation system with dependant field weakening control is introduced. The method of engineering design is used to choose the parameter of the controllers. The results are obtained from the MATLAB/SIMULINK simulation, which include the situations of the loads with sudden increase and sudden reduce. And the system response with constant-power load is also researched.
