Ball mill grinding circuit is a multiple-input multiple-output (MIMO) system characterized with couplings and nonlinearities. Stable control of grinding circuit is usually interrupted by great disturbances such as ore hardness and feed particle size etc. Conventional model predictive control usually cannot capture the nonlinearities caused by the disturbances in real practice.
