Level Control of Single Water Tank Based on Fractional-Order PIλControllers
摘要
Abstract
The application problem of fractional-order Piλ controller in the level control of single water tank was discussed, and a design method of Piλ controller was given based on a graphical stability criterion. The parameters stability region of Piλ controller was first determined, then, the performances of the closed-loop system were considered in the stability region, and a practical design algorithm was proposed also. Via Matlab simulation and the practical control test in the level control of water tank device, the control effects of fractional-order Piλ control, the conventional PI control and the Ziegler-Nichols tuning rule was compared. The results show the effectiveness of the design approach proposed and the superiority of fractional-order Piλ control over the conventional PI control.关键词
