The mill load of the industrial air-swept ball mill has till now been controlled by measuring the power consumption of the mill motor. Thus it was necessary to operate far from the range of optimal mill The mill load of the industrial air-swept ball mill has till now been controlled by measuring the power consumption of the mill motor. Thus it was necessary to operate far from the range of optimal mill filling. To improve the circuit performance alternative ways of mill load measurement were investigated.Zeng et al. established the mathematical model of duplex inlet and outlet ball mill system by taking the humidity of coal as an important parameter and adopted the extended state space predictive controller to control the multivariable system.

The conventional optimal tracking control method cannot realize decoupling control of linear systems with a strong coupling property. To solve this problem in this paper an optimal decoupling control method is proposed which can simultaneously provide optimal performance. The optimal decoupling controller is composed of an inner-loop decoupling controller and an outer-loop optimal tracking
