| 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 tun-ing 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. |
