基于MATLAB/Simulink双闭环直流调速系统的仿真研究

Research of Double-Loop DC Speed System Simulation Based on MATLAB/Simulink

分析了双闭环直流调速系统的工作原理,对相关参数进行计算,基于MATLAB/Simulink平台,建立了双闭环直流调速控制系统的仿真模型,仿真结果表明:用传递函数所建立的仿真模型,其响应的快速性,平稳性较好;以MATLAB中的power system模块所建立的仿真模型,其响应的快速性,平稳性稍差,但后者更能反映真实系统的响应过程,更有实际应用价值,因而具有一定的研究意义。

The double closed-loop DC drive system works are analysed in paper, and relevant parameters are calculated. There builds double closed loop DC control system simulation model based on MATLAB / Simulink platform. Simulation results show that： established simulation model based on the transfer function is better in the rapidity and smooth of response; although the power system simulation model based on the MATLAB is poor in the rapidity and stability of response, it has better reflection on the true system response process, more practical value, thus it has important research significance.
