Abstract
This paper describes a practical controller design using an acceleration reference for non-friction mechanism. To this date, the authors have proposed a nominal characteristic trajectory following controller (NCTF controller) using acceleration reference as a practical and user-friendly controller for precision motion control and examined the usefulness of the controller with friction mechanisms. In this paper, the design procedure of the improved NCTF controller using acceleration reference for non-friction mechanism is introduced and evaluated. A non-friction mechanism has a non-damping characteristic which influences the motion accuracy of the control system. The improved NCTF controller design is improved for the characteristic. The usefulness of the design procedure is examined with a non-friction mechanism comprising a linear motor and an air-slider.
