Abstract
A control system for controlling operation of a vibratory system and a tamper system of a paving machine includes a first input device, a second input device, and a controller. The first input device is operable to provide a first speed signal for operating the vibratory system at a desired first rotational speed. The second input device is operable to provide a second speed signal for operating the tamper system at a desired second rotational speed. The controller receives the first speed signal and the second speed signal from corresponding ones of the first and second input devices and compares the desired first rotational speed and the desired second rotational speed. Based on the comparison, the controller determines if the desired first and second rotational speeds lie within a pre-defined range from each other. Based on the determination, the controller modulates at least one of the first and second speed signals.
