Abstract:
A system for converting between a first operating mode and a second operating mode in a device, system comprising:a control loop which utilizes gain coefficients associated with the first operating mode to control the system in the first operating mode and utilizes gain coefficients associated with the second operating mode when operating in the second operating mode; a gain selector which causes the control loop to operate using the coefficients associated with the second operational mode at substantially the same instant that the device transitions from the first operational mode to the second operational mode, wherein the gain selector determines whether the control loop utilizes the coefficients associated with the first mode or the coefficients associated with the second mode based upon a current operational mode of the device; a gain table which is accessed by the control loop and contains the coefficients which are associated with a current mode of operation; and a smoother which smoothes the output of the control loop before a control signal created by the control loop is provided to the device, wherein the smoother adds a decaying offset value to the control signal.
