  • Estimation and control of the tool center point of a

    Booms of modern mobile concrete pumps are vulnerable to elastic vibrations due to the light-weight construction. Although these vibrations can be effectively damped with appropriate controllers, the residual movement of the tool center point (TCP) during the pumping process is still uncomfortable for the workers guiding the end hose.
