METHOD AND DEVICE FOR CONTROLLING A PHYSICAL QUANTITY HAVING A PROGRAMMED VARIATION WITH A FEED-FORWARD CONTROL

摘要

A method for the automatic control of at least one physical variable quantity in a controlled system is described, comprising the steps of: supplying a series of desired values (QI(t)) of said physical quantity; generating through an actuator (A) a series of real values (Qm(t)) of said physical quantity and measuring said real values; supplying to the actuator a feed-forward signal (vf(t)) to correct an error between the desired values of said quantity and the corresponding values thereof, that is obtained from the behaviour, over a time interval, of the desired values (QI(t)) of the physical quantity and of the dynamical behaviour of said controlled system.
