Abstract: The objective of this research was the development and evaluation of a control system used to compensate variation on angular speed of dosers in an equipment for formulation, dosing and application of solid fertilizers in the furrow, at variable rates, by monitoring the hydraulic oil temperature changes. PID controllers were designed to guarantee the desired angular speed of the hydraulic motors dosing shaft. The equipment was tested in laboratory using standard signal tests procedure, being able to analyze the machine behavior as a function of the hydraulic oil temperature variations. The accomplished tests showed that the implemented control system was suitable and exhibited a steady behavior even during hydraulic oil temperature changes.
