An optimal control system with data mining method for saving electricity

An energy conservation optimal control system using information network is presented in the paper. The special feature of the control system is to control total equipments in a factory for energy conservation at low cost using information networks. The control strategy consists of 2 parts. (1) Data mining algorithm to examine energy consumption for a factory. (2) Optimal control algorithm to control many manipulating values at the same time. The algorithm adopts model predictive control method. The system performance is tested through energy consumption simulations for the factory whose model is proved by the comparison with measured data for 1 month. Finally the system was proved to decrease energy consumption by more than 8% that is our final goal.
