Abstract
An exercise system includes a movable input member and a brake. The system further includes a controller that may be configured to control a resistance force of the brake acting on the movable input member to synchronize movement of the movable input member with a music beat. The controller may utilize a difference between a target speed and a measured speed, and a difference between a target phase and a measured phase to control the resistance force. One or both of the target speed and the target phase may be determined, based at least in part, on a music beat or other repetitive input.
Claims20
An exercise system comprising:
- a movable input member that is configured to move while a force is applied to the movable input member by a user;
- a brake configured to generate a resistance force that tends to resist movement of the movable input member when a user applies force to the movable input member;
- a controller operably connected to the brake, wherein the controller is configured to control the resistance force to synchronize movement of the movable input member with a music beat utilizing speed-based control and phase-based control, and wherein the controller is configured to implement the speed-based control and the phase-based control according to predefined criteria.
An exercise system comprising:
- a movable input member that is configured to move while a force is applied to the movable input member by a user;
- a brake configured to generate a resistance force that tends to resist movement of the movable input member when a user applies force to the movable input member;
- a controller operably connected to the brake, wherein the controller is configured to control the resistance force to synchronize movement of the movable input member with a music beat utilizing speed error and phase error, wherein the speed error comprises a difference between a target speed and a measured speed, and the phase error comprises a difference between a target phase and a measured phase;
- wherein the controller increases the resistance force relative to a baseline resistance force when:
- 1) the speed error is caused by the measured speed exceeding the target speed;
- and:
- 2) the phase error is caused by the movable input member being ahead of the target phase;
- and wherein the target speed and the target phase are determined, based at least in part, on the music beat.
A method of controlling an exercise device to synchronize movement of an input member of the exercise device to music, the method comprising:
- utilizing a music beat to determine at least one of a target phase and a target speed;
- utilizing phase-based control and a speed-based control to control a resistance force of a movable member of the exercise device while a force is applied to the movable input member by a user, wherein the resistance force is controlled in a manner tending to cause movement of the movable input member to be synchronized to a beat of the music;
- wherein the phase-based control comprises varying the resistance force in a manner that tends to minimize a difference between a measured phase and the target phase;
- and wherein the speed-based control comprises varying the resistance force in a manner that tends to minimize a difference between a measured speed and a target speed.
