Multiple-tension control using a new approach in signal-processing

A new tension control system is described, which allows the simultaneous control of up to four actuators, such as drives, brakes or clutches. It incorporates four speed/torque control modules and three tension control modules and is referred to as Multiple-Tension-Controller (MTC). All modules can be configured individually for different control schemes and can be interconnected to accommodate any type of application due to their formaI and universal character. A significant advantage of such a structure is that it allows the sharing of all related process variable values. This is used to decouple the individual controllers in order to improve the overall control behavior of the web machine. This proposed MTC shows how both simple and complex tension control systems can be configured and optimized in a global manner
