In a previous study, we constructed a passive speed control system using a functional brake for systems that are driven by an external force, such as that exerted by a person, water, or wind. Such systems vary widely and are difficult to predict. The functional brake employed an electrorheological fluid, was controllable and had a quick response. However, it was difficult to reduce the vibration of the response adequately. We thus used a functional clutch instead of the brake, and attached a motor to the driving shaft. The motor rotates constantly but in the direction reverse to the driving direction of the external force. We then constructed the speed control system by controlling the functional clutch and achieved lower vibration than when using a system having a brake. The present paper finally reports on isokinetic exercise equipment for a target system, which requires a speed control function when driven by the trainee.
