Summary:The automation of a double roller laboratory plant for continuous casting of thin steel strip is described. A nonlinear state-space process model which represents the dynamics of the solidification and forming process has been developed. Based on this model the control concept using the force as the controlled variable has been derived and applied to the plant. Furthermore, starting the process which is difficult to handle is treated as an optimization problem. The solution to this task is given as a nonlinear two-point boundary value problem which is solved by means of a gradient method. A multi-microcomputer system based on the AMS-Bus has been developed to handle the variety of all tasks of automation at the laboratory plant.
