CONTROL THEORY MODELS OF THE AGRICULTURAL SET (TRACTOR-POTATO PLANTER) DRIVER

Vehicle driven by operator may be considered as control system with driver as a controller and vehicle as controlled system. Changeable vehicle environment is the source of outer force reaching a driver and having effect on vehicle dynamics. Driver efficiency depends on situation on the road, vehicle characteristic and psychical and physical driver features. Driver is included in road-vehicle driver system as feedback element. His functions can be described as concerning running vehicle input data processing into control of vehicle systems. Parameters describing drives behaviour could be identified based on system model in frequency domain (from trans¬missibility) or in time domain (from correlation). The paper presents initial concep¬tion taking into consideration driver working in the tractor – agricultural machine set model.
