摘　　要：针对一阶大时滞系统响应速度慢和抗扰能力差的问题,提出了一种时滞削弱的自耦PID控制方法。该方法使用一种滞后时间削弱结构来降低大时滞系统的时滞时间,从而形成一个无时滞的一阶近似系统,并使用自耦PID(auto-coupling proportional-integral-differential,ACPID)控制理论来设计控制器,建立了ACPID控制器中速度因子的镇定规则,分析了自耦PID控制系统的鲁棒稳定性。仿真结果表明了所提出的控制方法的有效性,与现有控制方法相比,该方法响应速度明显提高,抗扰动鲁棒性更强,因而在大时滞系统控制领域具有广泛的应用价值。To solve the problem of slow response speed and poor disturbance rejection of first-order systems with large time delays,a time-delay attenuated auto-coupling PID control method is proposed.The method uses a time weakening structure to reduce the time delay of large delay systems,thus forming an approximate first-order system without delay,and to use auto-coupling proportional-integration-differential(ACPID).Based on ACPID control theory,the stabilization rules of velocity factor in ACPID controller are established,and the robust stability of auto-coupled PID control system is analyzed.The simulation results show the effectiveness of the control method.Compared with the existing control methods,the response speed is significantly improved and the anti-disturbance robustness is stronger.Therefore,it has a wide application value in the control field of large time delay systems.
