Aiming at the non-linear, time-varying and large delay characteristics of the phosphorus removal process from phosphate rock and the problems that the single PID control is prone to overshoot, this paper proposes a research method that combines fuzzy control technology with PID control, and designs a set of automatic control system for phosphorus removal from phosphate mine wastewater based on the adaptive fuzzy PID algorithm. Through an analysis of the past data, the membership function in the fuzzy PID controller is set, and the parameters in the fuzzy rules are modified in the real time so as to achieve the effect of self-adaptive optimization of control performance. MATLAB simulation analysis and experimental testing show that the control system has good stability and self-adaptability, and can achieve the effect of efficient use of phosphorus removal agents and economic efficiency.
