Paper Abstract

To reduce the low-frequency hydraulic-mechanical oscillations when a hydraulic crane boom system (HCBS) works, an improved PI control strategy based on fuzzy scheduling set-point weighting was proposed for the active damping control of a HCBS. By using a range camera and an electronic feedback control, the damping on the crane tip can be adjusted artificially. A co-simulation technique of HOPSAN and MATLAB is used in the controller design. Simulation results show that the proposed PI control system is with less overshoot and fast response. And the tip damping during HCBS working is improved.
