Modeling of the feedback control systems (driver-agricultural set) in aspect of movement safety

A control model of the agricultural machinery unit consisting of vehicle and agricultural machine has been presented. Vehicle driven by operator is being considered as control system with driver as a controller and vehicle as controlled system. Presented control system reproduces the actual behavior of the driver with its limited possibilities of perception, response time, delays, etc. Taking into account all the parameters describing such a behavior of the driver would not be possible. Therefore, it was decided to apply the method of describing the aggregate behavior by the use of the operational transmittance in the frequency domain and correlation in the time domain. The control model has been constructed with the use of stochastic methods and operational transmittances describing the various components of the system.
