| 摘 要： | 针对变结构控制的抖动、到达条件和趋近律等问题，分别在连续时域和离散时域进行了深入的研究，指出了减小抖动与提高鲁棒性之间的矛盾，提出了几种新型变结构控制律，结合泵控马达转速系统的控制，对积分变结构控制律进行了实验研究，验证了理论分析的正确性。

| Abstract: | Aiming at the chattering, reaching condition, and robustness of variable structure control, A thorough research is respectively carried out in continuous time field and discrete time field. The contradiction between increasing robustness and decreasing chattering is pointed out, and some new types of variable structure control law are put forward. Combining with the control of pump controlled motor rotational speed system, an experimental study for integral variable structure control law is performed, the rightness of theoretical conclusions is verified. |
