| Abstract:In the process of pulping, the cutter control of disc refiner affects the quality of the pulp directly.PID control algorithm is widely used in paper industry because of its characteristics of simple structure and easy to implement. But PID parameter is difficult to set and easy to produce super harmonic and oscillation, which could often cause knife collision problem in disc cutter control, making the disc plate to wear, then influence the normal production of pulp. Based on the basic ant colony algorithm, this paper presented an improved ant colony algorithm and used it to set the PID parameters, this method overcomed the problem of over reliance on artificial experience and time consuming.MATLAB simulation results showed that the method could find the optimal control parameters quickly and accurately． |
