Using the Bezier Curve and Particle Swarm Optimization in Trajectory Planning for Overhead Cranes to Suppress the Payloads' Residual Swing
2018
Mathematical Problems in Engineering
Preserved Fulltext
The dynamic equation for an overhead crane is discredited, and a five-order Bezier curve is generated as the trolley's displacement. ...
This paper proposes a trajectory planning approach which uses the Bezier curve and particle swarm optimizer (PSO-BC) to limit the residual swing of a payload. ...

For decades, de Casteljau's algorithm has been used as a fundamental building block in curve and surface design and has found a wide range of applications in fields such as scientific computing, and discrete ...
With increasing interest in nonlinear data science, its constructive approach has been shown to provide a principled way to generalize parametric smooth curves to manifolds. ...
Several traditional applications of Bézier curves can also be found for their manifoldvalued generalizations: They have been used, e.g., for curve modeling (Morera et al., 2008; Sharp and Crane, 2020; ...

In contrast to local collision detection strategies used in, e.g., physical simulation, this energy considers interactions between all pairs of points, and is hence useful for global shape optimization ...
