Abstract
The test subjects were asked to push forward force-operating-joystick while listening to white noise with square envelope. The sound and the operating force measured simultaneously. It was cleared that there were variations of operating force depending on experimental date and individual. We have built a system that has auditory-feedback control system for the operating force to follow set point. We performed experiments on fixed command control using PI controller with various control parameters. The appropriate control parameters for individual were discussed using three parameter-tuning methods. Consequently we found that Cohen-Coon's parameter-tuning method was most appropriate in the system.
