摘要:為了提高直流調(diào)速系統(tǒng)的動態(tài)、靜態(tài)性能，我們通常使用閉環(huán)控制系統(tǒng)（主要有單閉環(huán)、雙閉環(huán)）。而在對調(diào)速指標要求不高的場合，采用單閉環(huán)即可。相比較于開環(huán)系統(tǒng)，閉環(huán)系統(tǒng)能自動檢測，把輸出信號的一部分送回到輸入端，與輸入信號相比較，把差值作為實際的輸入信號，它能自動調(diào)節(jié)輸入量，提高系統(tǒng)的穩(wěn)定性。 在對調(diào)速系統(tǒng)性能有較高要求的領域下，我們常會使用直流電動機，由于直流電動機開環(huán)系統(tǒng)的穩(wěn)定性不能夠滿足要求，但可利用轉速單閉環(huán)提高穩(wěn)態(tài)精度，而采用比例調(diào)節(jié)器的負反饋調(diào)速系統(tǒng)仍是有靜差的，如果要消除系統(tǒng)靜差，可采用積分調(diào)節(jié)器代替比例調(diào)節(jié)器。 本文將重點探討單環(huán)有靜差轉速負反饋調(diào)速系統(tǒng)，畫出仿真模型，利用MATLAB/SIMULINK工具箱，對控制系統(tǒng)的電氣原理結構圖進行調(diào)速系統(tǒng)的建模與仿真。 關鍵詞：直流調(diào)速系統(tǒng)；單閉環(huán)；靜差；MATLAB/SIMULINK
Abstract:In order to improve the DC speed control system dynamic and static performance, usually adopts closed-loop control system(mainly includes single closed loop, double closed loop).And in not high demand on the speed regulation index of occasions, the single closed loop can.The closed-loop system than the open loop system can automatically detect the part of the output signal back to input, compared with the input signal, the difference value as a practical input signal and input of can adjust and improve the stability of the system. On the speed regulation system performance in higher demand for DC often used the field, but for DC open loop system stability not can meet the requirements of, can use speed closed-loop improve single steady precision, and the proportion of the regulator is still have negative feedback speed regulation system static poor, in order to eliminate system static poor, can use integral regulator instead of proportion regulator. This artical will focus on the single ring static speed negative feedback regulation system, draw the simulation model using MATLAB/SIMULINK toolbox on the control system of the electrical principle diagram of control system modeling and simulation.
