Abstract
An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.
Claims22
An exercise machine, including:
- an actuator;
- a motor;
- a cable coupled between the actuator and the motor;
- and
- a motor controller coupled to the motor, wherein the motor controller is configured to:
- control the motor according to a weight stack filter that is configured to emulate a behavior of a weight machine with a weight stack to the actuator;
- and
- control motor torque based at least in part on a modeled acceleration of the weight stack determined based on a tension of the cable and gravity.
5 more elements
A method, comprising:
- controlling, by a motor controller, a motor according to a weight stack filter that is configured to emulate a behavior of a weight machine with a weight stack to an actuator, wherein the motor controller is coupled to the motor, and wherein a cable is coupled between the motor and the actuator;
- and
- controlling motor torque based at least in part on a modeled acceleration of the weight stack determined based on a tension of the cable and gravity.
