| Abstract: | Flotation is a key process in mineral processing production,in which flotation level must be strictly controlled to ensure high metal recovery rate.A PID controller(IMC-PID) which is designed based on Internal Model Control(IMC) is applied to bring flotation level under automatic control.The model has such advantages as simple structure,few adjustable parameters and strong robustness.Moreover,the basic principle and design method of IMC-PID are introduced,and a flotation level control system is presented.The practical application indicates that the system has improved the metal recovery rate,which ensures fine quality of ore grade,thus having broad implications. |
