Ball mill grinding circuits are essentially multi-variable systems characterized with couplings, time-varying parameters and time delays. The control schemes in previous literatures, including detuned multi-loop PID control, model predictive control (MPC), robust control, adaptive control, and so on, demonstrate limited abilities in control

An improved control strategy is proposed to control ball mill grinding circuits for energy saving and pollution reduction. A two-layer optimization architecture combined by particle size optimization layer and energy optimization layer is developed, where the optimal particle size set-point is
