A non-woven cross-lapper machine uses the pulley block structure to pull the pulley
bracket, which folds out the required web thickness and width of the non-woven products
by the reciprocating motion of the pulleys. The system needs to move back and forth at a
stable constant speed, and be able to stop at the precise position of the re-entry point
when reciprocating. This paper deals with the modeling and control of the current new
horizontal type cross-lapper machine. The Lagrange’s equation is applied to derive the non-
linear dynamic equation of the system. In the controller design, this study first obtains the
transfer function of the high-order linearization system. Then, the approximation criterion is
used to obtain the corresponding low-order system transfer function, so that the analysis
and design effort is reduced. Both the realizable proportional and integral control, and pole-
placement design through state feedback, are applied for the control system design. The
performances of the designed controllers are verified through computer simulation.
