摘　　要：本文提出一种新型调节器方案－组合调节器。变结构控制器（ＶＳＣ）和ＰＩＤ调节器两种不同的调节器通过可变的加权因子组合起来，克服了ＶＳＣ在滑模线原点附近的高频颤动，提高了稳态精度。同时使直流ＰＷＭ伺服系统实现了无超调、无振荡，具有良好的鲁棒性和快速性，无静差和极强的抗扰动能力。调和了动态与稳态性能之间的矛盾。组合调节器用１台ＭＣＳ－５１单片微机实现。本文给出了实验结果。A new regulator scheme,i. e. association regulator is proposed in this paper. This regulator is composed of a variable structure controller and conventional PID regulator by variable Weighted factor. The high frequency quiver of VSC in an original point nearby of the sliding mode linear is overcomed. The steady precision is increased. A DC PWM servo system possess the advantages of good robustness non overshoot.non oscillation and fast response. The association regulator is implemented in a MCS- 51 single chip computer.
