Abstract :
To maintain uniform string tension and arrangement during the winding shaping process of automobile belt, a digital control system is proposed. The tension is measured by a transducer and regulated by a magnetic powder brake, while the velocity of the shaping model shaft is measured by an opto-coder and driven by a DC motor. In this paper, we present H2-optimal control. First, system is derived as a 5-order, 2-input and 2-output state space model. Then the system is discretized, and H2-optimal control is realized by following steps: constructing standard sampled-data system; constructing all stabilizing controller; H2-optimal control with desired step tracking.
