Abstract

To address the issues of high peak power demand and low energy conversion efficiency in electric quay cranes at ports, a method for trajectory planning and path power optimization control of electric quay cranes is proposed. The energy coupling conversion relationship and operational characteristics of electric quay cranes are analyzed, from which the dynamic equation is derived. Considering the environmental constraints during the working process of electric quay cranes, a B-spline curve is used to design the operation trajectory of electric quay cranes. The relationship between path power transmission and conversion of electric quay cranes is analyzed, and in combination with the system dynamics, a quantitative description relationship between the operating trajectory and path power is determined, forming an electric quay crane trajectory-power model. The trajectory of electric quay cranes is optimized with the objective of minimizing total electricity consumption, which results in a reduction of path power loss. Simulation examples are established in MATLAB, and the method proposed shows significant improvements in the path power optimization control of electric quay cranes under different working conditions, demonstrating its effectiveness and reliability.

Key words： electric quay crane; trajectory planning; B-spline curve; path power; optimization control
