Theoretical Control and Experimental Verification of Carded Wed Density Part II: Pole Placement Design Through State Feedback

摘要

A modern control strategy including controller deisgn and system output modification is illuminated by application to feedback control of a carded web control system. Since the carded web system is a type-zero plant, an integrator in the feedforward path between the error comparator and the plant is inserted to improve the sytem type. A new controlloability property is the key in the application of this kind of control system design technique. At the same time, the computer simulation result is proved by theoretical analysis. A performance comarison is made of the conventional cotrollers versus this modern control scheme, and teh performance of the new contro strategy is effectively demonstrated by computer simulations.
