摘要: Mathematical modeling as well design of proper process controllers for web handling systems requires knowledge the system dynamics or observations from an actual system. The dynamic behaviour a is defined by interactions between flexible web, rollers and electric drives. In this paper, offline-identification transport subsystem considered. identification carried out exciting controlled with pseudo-random binary signal (PRBS) torque reference. A discrete time polynomial model Output-Error (OE) structure used in time-domain process. Moreover, paper investigates tension position controls intermittent controller designed identified reference H∞-loop shaping. Validation influence improvement are verified through experimental tests.
