摘要：
A wisdom proportional-integral (WPI) control method which does not depend on the model and attribute of the controlled objects was proposed for the control problem of first-order systems with time-delay. The WPI control method uses speed factor to closely link the proportional and the integral link to form a collaborative control core. The theoretical analysis showed that the closed loop control system composed of WPI controller is globally asymptotically stable. Numerical simulation results showed that the WPI control method is effective in response to not only fast response speed and high control accuracy, but also good disturbances rejection robustness, which has wide application value in the field of time-delay system control. © 2019, Editorial Department of Control Theory & Applications South China University of Technology.
