Abstract

With modern demands for quality cold rolled steel, there is often a need to improve or test of optimality
of the existing system of regulation of the strip thickness. For these purposes, there is needed the model to minimize the
amount of field experiments. The purpose of system of automatic regulation of the strip thickness at the housing screws
of the first stand is maintaining of minimum deviation from the desired thickness behind the first stand. Such regulators
operate as a function the thickness deviation behind of the first stand and respectively have a transport delay
measurement control parameter. Model synthesized in modeling complex Simulink Matlab software package (version
7.4.0.287 R2007a), and adjusted for the speed of the first stand V1 = 5,7 m / s, the thickness of 1,7 mm. To assess the
adequacy of the model was comparable testing of an identical impact actual object and the model. There were fixed
graphics of three parameters: the deviation of thickness behind 1stand %; RTC output, % (reference to the drive); the
absolute position of one of the two housing screws of first stand, mm. The resulting model is adequate to the actual
controller of the strip thickness and can be used for debugging and setting of real system of automatic regulation.
