【Abstract】 According to the experimental results of the static and dynamic performance of the electrode servo control system of an electrical furnace in a steel plant, we identify the mathematical model of the valve controlled cylinder system with deadband nonlinearity. The identification denotes that the dry friction deadband can be expressed as a negative feedback of cylinder velocity with gains of T/ \VP\ . This method of experiment and identification can be used to analyze the other electrode servo control system of electrical furnace.更多还原
