Abstract

A method for controlling a variator system of a machine is disclosed. The method includes storing a plurality of work cycle patterns associated with an operation of the machine in a memory module of a control system, and determining operating parameters of the machine based on inputs from a plurality of machine sensors. The method further includes classifying the current work segment as one of the plurality of predetermined work segments and determining an error value based on an actual output speed and a desired output speed of the variator. The method further includes determining a closed-loop gain value corresponding to the current work segment and the error value. The method further includes implementing the determined closed-loop gain and the determined current range to the actuator to adjust position of a swash plate of the variator, to control an output speed of the variator.
