Abstract
Grinding circuit (GC) of mineral processing industry is characterized by its multivariable, high interacting, time-varying parameters and large measurement delay nature. The product particle size and the circulating load of the GC are two important production indexes that directly related to performances of the subsequent beneficiation process and production rates of the overall mineral processing plant. However, they are usually difficult to be controlled effectively with conventional control strategies due to the above mentioned complex characteristics. In this paper, a modified analytical decoupling control (ADC) scheme is proposed to handle such an intricate multivariable process with large output delay. Control studies have been performed by simulation tests for setpoint tracking, disturbance rejection and robustness problems.
