Abstract
Torque that is requested of a motor to generate an experienced inertia different from a mechanical inertia of an actuator is adjusted, wherein the experienced inertia is a flywheel inertia model. In one embodiment, the motor provides resistance to the actuator. In one embodiment, the actuator is coupled to the motor.
Claims20
An exercise device, comprising:
- a motor that provides resistance to an actuator coupled to the motor;
- and
- a torque controller configured to:
- adjust torque that is requested of the motor to generate an experienced inertia different from a mechanical inertia of the actuator based at least in part on a comparison of a velocity of the actuator to the determined rotational speed of an emulated flywheel,
- wherein the experienced inertia is a flywheel inertia model and the flywheel inertia model comprises a state space model of the emulated flywheel.

A system for emulating a flywheel using a motor, comprising:
- a motor that provides resistance to an actuator coupled to the motor via a cable;
- a processor configured to:
- use a state space model of an emulated flywheel to determine a rotational speed of the emulated flywheel based on tension of the cable and speed of the cable;
- and
- a torque controller configured to:
- adjust motor torque to generate an experienced inertia different from a mechanical inertia of an actuator based at least in part on a comparison of a velocity of the actuator to the determined rotational speed of an emulated flywheel,
- wherein the experienced inertia is a flywheel inertia model and the flywheel inertia model comprises the state space model of the emulated flywheel.
