Abstract :
A fuzzy system is used to weigh alloy metal into electric arc furnace and implemented by using ladder program for programmable logic controller, where weight error and its derivative are used for input variables and vibration amplitude of alloy bin is used for output variable. This control system is applied to the plant and results in higher measuring accuracy as well as faster measuring term than conventional on-off control system.
