单闭环直流调速系统的设计与仿真单回路的直流调速系统的设计和仿真内容摘要：在对调速性能有较高要求的领域，假如直流电动机开环系统稳态性能不满足要求，可利用速度负反馈提高稳态精度，而采纳比例调节器的负反馈调速系统仍是有静差的，为了消除系统的静差，可利用积分调节器代替比例调节器。 通过对单闭环调速系统的组成部分可控电源、由运算放大器组成的调节器 、晶闸管触发整流装置、电机模型和测速电机等模块的理论分析，比较原始系统和校正后系统的差别，得出直流电机调速系统的最优模型。然后用此理论去设计一个实际的调速系统，并用 MATLAB 仿真进行正确性的验证。关键词：稳态性能 稳定性 开环 闭环负反馈 静差The design and simulation of Single loop dc speed control systemAbstract :In the higher demand for performance of speed, if the open loop dc system's steady performance does not meet the requirements, can use speed inverse feedback to improve steadystate precision, but although the speed inverse feedback system adopts proportion regulator,it still have off, in order to eliminate static, can use integral regulator to replace proportion regulator. Based on the theoretical analysis of the single closed loop system which is made up of controllable power, the regulator which is made up of operational amplifier, a rectifier triggered by thyristor , motor model and tachogenerators module, compare the difference of the open loop system and the closed loop system,the original system and the this paper compares the theory of open loop system and the closed-loop system, the difference of primitive system and calibrated system, conclude the optimal model of the dc motor speed control system. Then use this theory to design a practical control system, and verify the validity with MATLAB simulation.Key words: steady-statebehaviour stability open loop Close-loop feedback offset精品文档---下载后可任意编辑目 录1 绪 论................
