Genetic algorithm based optimization of asymmetric s-shape acceleration/deceleration for biaxial motion systems

In this study, an optimization algorithm is proposed for asymmetric s-shape acceleration/deceleration to achieve better contour accuracy for biaxial systems. The optimization is based on the method of genetic algorithm incorporated with the constraints made by the motion system. Numerical simulations of an XY table driven by linear motors following a simple cornering path verify the proposed algorithm.
