衡量一个速度控制系统性能优劣的指标,一般分为稳态指标、动态指标和抗扰动性指标。转速电流双闭环调速系统是最典型的直流调速系统,利用电流调节器和转速调节器控制,可以无限逼近理想启动过程。本文分析了系统的控制原理,建立了系统的动态数学模型,并利用MATLAB中的Simulink进行了系统建模仿真给出仿真结果。通过对结果的分析进一步验证了双闭环调速系统的优越性。

ABSTRACT
Measure a speed control system performance indicators, generally divided into static, dynamic and disturbance resistance index. Speed current double closed loop speed control system is the most typical dc speed control system, using current regulator and speed regulator to control, can be infinitely close to the ideal start-up process. This paper analyzes the control principle, to establish the dynamic mathematical model of the system, and system modeling simulation is carried out using the Simulink of MATLAB, the simulation results are given. Through the analysis of the results further verify the superiority of the double closed loop speed regulation system.
