基于SIMULINK的转速单闭环直流调速系统的仿真

摘要

为了提高直流调速系统的动静态性能指标，通常采用闭环控制系统（包括单闭环系统和多闭环系统）。对调速指标要求不高的场合，采用单闭环系统，而对调速指标较高的则采用多闭环系统。按反馈的方式不同可分为转速反馈，电流反馈，电压反馈等。在单闭环系统中，转速单闭环使用较多。%Closed-loop control systems, including single and multi-loop, were usually used to improve the dynamic and static performance of DC drive system. Single closed-loop system was used in the applications of speed index for low requirements, while multi-loop system was used for high requirements. It can be divided into speed, current and voltage feedback according to different feedback ways. Speed feedback was used more in single closed-loop system.
