摘要
对双闭环直流电机调速系统进行设计改进,对原双闭环调速系统进行建模与仿真,仿真结果表明系统的阶跃响应是稳定的,但超调量过大。针对该结果提出基于微分负反馈的系统改进方案,仿真结果表明超调量有效地降低,达到了改进目标。所以基于微分负反馈调节不仅可使直流电机的双闭环调速系统稳定且系统响应速度较快。
Aim to improve a double closed-looped speed model is also built based on the mathematical model. The indicates system step response is stable but the overshoot negative feedback is proposed, The overshoot method based on differential negative feedback regulation system for DC motor. Simulation result of simulation speed regulation system is too high. A solution based on differential of improvement system is much low. Therefore, the regulator guarantees both stable and rapid response of the double closed-looped speed regulation system for DC motor.
