| 摘 要： | 提出了一种新型的大纯滞后系统的控制方案，该方案无需根据被控对象做出精确的预估模型，仅用常规的PI调节器即可实现系统的控制，仿真试验结果表明：在随动和可测干扰情况下，大纯滞后不影响系统的控制效果和稳定性，系统对于被控对象参数的变化不敏感；系统的抗干扰能力比传统大纯滞后控制方案有了较大提高，干扰可被迅速消除。

| Abstract: | In this paper a new control scheme for time-delay systems is put forward, in which the precise models are not necessary and the control law can be achieved by PI controllers. The simulation results show that the time delay does not influence the system' s stability and control in the servo system and regulator system; the system is insensitive to the variability of plant parameters; and the ability of disturbance-rejection is better than the conventional scheme. Finally, the disturbance can be rapidly eliminated. |
