In this paper, the results of research on the control system of flotation tailings content and flotation reagent consumption control system with different control structures are introduced. The following control algorithms are used in the study: Predictive Controller, Philips Semiconductors Controller, P, PI, PID Controller. The analysis of these algorithms uses a simulation based on a mathematical model of flotation mechanical dynamics. Discusses the parameter design rules of the control algorithm, and determines the relevant control evaluation criteria of the best structure and control algorithm.
