基于 MATLAB 的双闭环直流调速系统建模与仿真
Modeling and simulation of double closed loop DC speed control system based on MATLAB
摘要
Abstract
Combined with the rotate speed and current double closed-loop DC speed regulating system,the sys-tem structure and the circuit composition process the modeling and simulation,using the simulation software Simulink of double closed-loop DC speed regulating system current loop.The results show that the greater the damping coefficient,the larger the overshoot amount and the shorter the rise time.When the damping coefficient is 0.5,the current loop performance is best.In the optimal performance of current loop and at no-load running conditions,the system steady speed changes smaller over a given smaller voltage.At the rated loading condi-tions,through a long rise time,the system will be at the rated speed.Disturbance rejection test shows that the system has a stronger resistance to interference.关键词
