A servo control system is presented that provides improved bandwidth. The improved bandwith is achieved by dividing the differential portion (20) of the servo control system into two components. One of the differential components (22) experiences no delay thus improving the servo control system response. The differential component that experiences no delay is combined with the proportional portion (18) of the control system and is implemented as an analog circuit. The hybrid analog/digital loop compensation circuit provides even better response time as the analog circuit provides near instantaneous responses to changes in input.
