Power transmission
A power servo system is described which includes actuator means adapted to variably actuate a load. The actuator means having a predetermined first polynomial transfer function in the sampled-data domain having a plurality of first constants related to dynamic behavior characteristics at the actuator means, and sampled-data servo control means including means for receiving a command signal, sensor means responsive to the actuator means for providing a sensor signal as a function of actuation at the actuator means, and means for providing an error signal to control the actuator means as a combined function for the command signal and the sensor signal to obtain a preselected response characteristic at the actuator means characterized in that the means for providing the error signal comprises: means for periodically sampling the sensor signal to provide a sampled sensor signal, feedback compensation means receiving the sampled sensor signal and having a preselected second transfer function coordinated with the first transfer function to obtain the preselected response characteristics, the second transfer function in the sampled-data domain being a polynomial having a number of second constants which vary as functions of the first constants, first means for estimating the first constants, second means responsive to the first means and coupled to the feedback compensation means for calculating the second constants as a function of estimated first constants, means responsive to the feedback compensation means and to the command signals to provide the error signal.
