Cable control and operation in a motorized fitness machine

Abstract

A cable-operated exercise machine providing slack-compensating control of resistance force applied to a tension cable, the exercise machine comprising: the tension cable, configured to receive user force applied by pulling on a user end of the tension cable; a resistance motor applying the resistance force to a motor-coupled end of the tension cable, in opposition to the user force; and a controller comprising processing circuitry configured to: access data indicative of a momentum of components of the exercise machine, wherein the momentum of the components is coupled to movement of the motor-coupled end of the tension cable; determine an adjustment to the resistance force, wherein a size of the adjustment is determined, in accordance with the indicated momentum, to compensate against slack distance developing along the tension cable consequent to a potential rapid reduction in the user force; and signal the adjustment in resistance force to the resistance motor.
