A recently granted patent (Publication Number: US11840426B2) discloses a large manipulator for concrete pumps featuring a distributor boom with articulated boom arms controlled by a sophisticated control apparatus. The control system includes various devices such as a vertical speed determining device and an angle determining device to manage the movement of the articulated boom. The patent details a distributor boom damping routine that calculates damping forces and control variables based on physical variables of the distributor boom and articulating angles of the joints. Additionally, a controller assembly runs routines like a distributor boom target posture value routine and a superimposition routine to convert control signals into target posture values and control the actuating elements of the drive units effectively.

Furthermore, the patent describes methods for damping mechanical vibrations of the articulated boom, involving determining vertical and horizontal speeds of the boom arm location, articulating angles of the joints, and actual forces or torques generated by the drive units. The control apparatus utilizes this information to calculate damping forces, target speeds, and comparison values to effectively control the movement of the articulated boom. The methods also involve converting actual posture values into controlled posture values for the actuating elements of the drive units, ensuring precise and efficient operation of the large manipulator for concrete pumps. Overall, the patent highlights advanced control mechanisms and routines to enhance the performance and stability of large manipulators in concrete pump applications.
