Abstract
Methods and apparatus for automatic estimation of output mapping parameters for a control system where those output mapping parameters may be estimated from changes in sensor input data when the control system enters steady-state motion. Methods and apparatus for automatic estimation of minute ventilation at anaerobic threshold and minute ventilation at peak exercise for adjustment of rate-adaptive curves of pacemakers. The methods include detecting steady-state motion of the pacemaker and calculating minute ventilation at anaerobic threshold and minute ventilation at peak exercise from changes in minute ventilation sensor data corresponding to the period of steady-state motion.
