Play floor control system by feedback linearization technique

摘要

The present invention is to maintain the height of the hot water in the continuous casting line and billet factory in a desired position, the performance by the feedback linearization (Feedback Linearization) control technique to stably control the hot water even if disturbance (Disturbance) in the player It relates to a water level control system.;The control system of the present invention includes a tundish weight sensor 10 which detects the weight of the tundish and sends a signal for the amount of variation to the controller, a radiation level sensor 4 for detecting the mold floor, and a signal for the casting speed. Opening area of the sliding gate (2) receiving a reference to the casting speed detector (11), which transmits the signal to the controller (12), the signal for the tundish weight, the signal for the casting speed, and the signal for the actual height for the elevation height and the reference signal. And a controller 12 for generating a control signal by determining a control amount for the controller.;Where A _v is the opening area of the sliding gate, A _m is the mold size, V _cs is the casting speed, C is the friction coefficient for fluid flow in the deposition nozzle, 1 is the height of the metal in the tundish, a is a constant, h is the structure which calculates a control amount based on the level of a standing surface, and h _d is a reference height of a standing surface.
