Abstract : The patent relates to a servo system which obtains error signals from a sample and hold system. A rate feedback is provided from the output of a servo, and achieved parameter signal is fed back to the sample and hold system to correct the error signal upon the next sample interval. A feedback to the input of the servo system is provided by an integrator which integrates the rate of change of the servo system's parameter each sample interval.
