Motion design and implementation for a hybrid drive system

Abstract

This paper presents a study of motion design and its implementation on a hybrid drive system that combines the motions of a large constant speed motor with a small servo motor by means of a mechanism in order to provide a powerful programmable drive system. In general, the most suitable function used to generate motion curves is the power form of polynomial functions. However, this function may produce some unexpected oscillations between the boundary conditions. A methodology is given to prevent this drawback of the interpolation function. A laboratory type set-up is designed and manufactured in order to realize the problems of practical implementation. An experimental application involving the hybrid drive system is included in the study presented.

Design of hybrid machines for nonuniform motion production

“…The optimized design showed that theoretical savings of 70 per cent in peak servo motor power could be achieved with the hybrid concept compared to a direct drive case in which the servo motor provided the required motions directly. A general method for the design of motion trajectories and its implementation in an experimental hybrid machine has recently been reported [4].…”
