On the basis of analysis of the different characteristics between process industries and discrete manufacturing industries, as well as the different targets of smart manufacturing, a meaning for smart optimal manufacturing for process industries aimed at high efficiency and greening is proposed. The developmental direction of industrial process control systems is smart optimal control systems.
Ball mill grinding circuit is a multiple-input multiple-output (MIMO) system characterized with couplings and nonlinearities. Stable control of grinding circuit is
The direct-fired system with duplex inlet and outlet ball mill has strong hysteresis and nonlinearity. The original control system is difficult to meet the requirements. Model predictive control (MPC) method is designed for delay problems, but, as the most commonly used rolling optimization method, particle swarm optimization (PSO) has the defects of easy to fall into
Grinding circuit must provide stable particle size distribution and should also operate in a way to maximize mill efficiency. Fuzzy logic based on-line optimization control integrated in an expert system was developed to control product particle size while enhancing mill efficiency in a ball mill grinding circuit. In the supervisory level, fuzzy logic control determined the optimum set
