Abstract

A polymer fiber spinning process is modeled for a draw resonance controller design. We present a second order nonlinear dynamic model which can predict the draw resonance instabilities. Using this model a nonlinear control system is designed in order to eliminate the draw resonance instabilities at high draw ratios. We present successful simulations of three different control laws based on conventional linearization of nonlinear dynamics, exact linearization technique under some simplifying assumptions, and Lyapunov design technique
