摘 要:Unmeasurable velocities and noise amplification by numerical differentiators are difficult problems for crane *** this paper,an adaptive controller,without velocity feedback,is proposed for 3-D ship-mounted cranes to achieve swing suppression and accurate boom positioning. Auxiliary variables are designed to substitute for velocities that cannot be obtained directly. Additionally,bounded functions are utilized to constrain the input torque for safety. The stability of the control system is rigorously proven using Lyapunov s method. Furthermore,simulations validate the effectiveness of the proposed method.
