Attempts on the Performance Improvement of the Manual Auditory Feedback Control Systems

It has been pointed out in several foregoing literatures that the well known properties of the human pilot observed in the manual visual feedback control system can also be observed in the manual auditory feedback control system. However, performance of the manual auditory feedback control usually tends to degrade as compared to the visual feedback case. In this paper, some experimental attempts to improve the maneuverability of the manual auditory feedback control system are presented. Several differently configured auditory displays and the use of phase lead compensator are proposed and evaluated using the artificial manual auditory feedback tracking control system. Experimental result indicates that performance improvement can be achieved to some extent; however, the effectiveness of the applied auditory devices and/or lead compensator largely depend on the plant characteristics
