TECHNOLOGICAL FEATURES OF AUTOMATIC CONTROL OF LONG FIBRE PRODUCTION
Machines for producing flax fibre as automatic control objects are described in this article. Versions of control of drying machine by control of amount of supplied heat, intensity of replacement of spent drying agent with fresh one, change of drying agent speed in drying region, change of material movement speed in drying space are considered. It is shown that what is the most rational way of controlling the moisture of retted straw is the way that uses a closed control system with negative feedback. The block diagram of the automatic drying control system that acts on the control object, in this case on the dryer, through the actuator, in order to reduce the amount of humidity deviation depending on the amount and the sign of deviation, is developed.
