Abstract :
A technique of using a hysteresis element for velocity feedback in order to obtain ideal responses without the influence of the target height is proposed. The application of this control technique to actual control systems was studied through various types of simulation and experiment. It was confirmed that the control technique provides excellent compensation. It was found that the principle of posicast control which is not influenced by the input intensity can also be applied to positioning servo systems with saturation characteristics. If the hysteresis element is provided with a function for prediction, hysteresis feedback control has the same compensation effect on a high-order servo system with the behavior of a second-order damped-vibration system as on a second-order servo system
