Implementation of Fuzzy Adaptive PID in Thickener Flocculation Dosing Control System Based on Properties of Mining Materials

Abstract:

Lead sulfide solid particles floated from ore are small, hard to concentrate. Thickener flocculation dosing control system is non-linear process control system. This paper studied a mining thickener dewatering control system, with the middle concentration detection technology, PID and the fuzzy control theory research combined, and designed the polymer flocculant dosing fuzzy adaptive PID controller. It completed the simulation study by MATLAB/simulink. The result indicates that this control method responses fast and virtually has no overshoot. It can reduce the flocculant dosing, decrease the overflow density, reach energy conservation emission reduction, and cost saving.
