Parameters Design based on MATLAB for DC Speed Regulation System

本文以线性二次型最优控制设计方法为基础,通过MATLAB仿真工具对双闭环直流调速系统的速度环进行动态设计。文中通过选择最优的加权矩阵,使设计得到的调速系统获得了良好的控制性能,并结合煤矿直流提升机系统的实际应用,给出了系统响应波形。

Dynamic design method of velocity loop in double-loop DC speed regulation system is presented in this paper. It is on the basis of the linear quadratic optimal control design method and with the help of MATLAB simulation tool. By choosing optimal weighting matrix, the designed speed regulation system achieves excellent performance. The system response waveforms of the actual mine hoist system are given in the paper.
