Abstract :
The application of a multivariable regulator to a hot strip finishing mill is considered. The need for multivariable control is due to the interactions between the strip thickness, tension and the angle of the looper arm. A much improved performance was obtained by designing a controller which takes account of the interactions effectively which a conventional control strategy fails to achieve. The structure of the physical process models are used to choose the control structure to prevent it being too complex
