Abstract: A
step-by-step electro-hydraulic servo system is presented for improvement
of the head of band in a hot rolling mill for offering a cost saving.
Including the position-adjusting loop and the pressure-adjusting loop,
this system applies a simplified Hm mixed sensitivity algorithm to the
closed-loop shaping. The core of the algorithm is to shape T, tire
transfer function of the closed1 loop system, then the controller K is
directly designed without selection of any weighting function, The
result shows that with the algorithm, (lie Ha, controller obtained is
effective for the step-by-step control system.
Key words: H∞ controller
