According to one or more embodiments, a steer by wire steering system includes a handwheel actuator, a roadwheel actuator, and a resynchronization module to dynamically adjust handwheel position that is used for rack position reference calculation. The dynamic adjustment includes determining a desynchronization amount based on a difference in an actual handwheel position and a synchronized handwheel position. The dynamic adjustment further includes computing a handwheel adjustment using the desynchronization amount, a vehicle speed, and a handwheel speed. The dynamic adjustment further includes computing an adjusted handwheel position based on the handwheel adjustment and the actual handwheel position. The dynamic adjustment further includes updating the reference rack position based on the adjusted handwheel position. The dynamic adjustment is continuously repeated until the handwheel adjustment is substantially equal to zero.
