Abstract

The continuous steel casting is an important link in steel production. The performance of mold level control for the continuous steel casting affects the steel quality directly. The main difficulties for mold level control are that the continuous steel casting has big uncertainties and grave nonlinearities, and the continuous steel caster runs in its hot and hostile environment. In this paper, the neuron model-free control method with fuzzy tuning gain is proposed for continuous steel casting processes. In this control system, the neuron controller is used to control the mold level and the fuzzy algorithm to tune controller gain. According to the system operation conditions, the fuzzy rule base is updated to improve control performance. The experiments are made to demonstrate the effectiveness of the proposed controller.
