Abstract :
Demand for improved performance under a wide variety of dynamic conditions and web materials are placing additional emphasis on developing new advanced control strategies. This paper presents decentralized Hinfin controllers with model based feedforward for web winding systems which provide improved web tension and velocity regulation in the presence of uncertainties. First, mathematical models of fundamental elements in a web process line are presented. A new state space model is developed which enables calculation of the phenomenological model feedforward signals and helps in the synthesis of decentralized Hinfin controllers around the set points given by the reference signals. Different Hinfin control strategies with additive feedforward have been validated on a nonlinear simulator identified on a 3-motor winding test bench
