Control strategy crushing circuits electriciteforbach

strategies when applied to a crushing circuit to control conveyor power and bin level. Comparison was made by examining the effectiveness and the level of effort required to commission and tune each control strategy. This was performed by applying the control strategies to a dynamic model that was configured in the MATLAB/Simulink platform.
