Linear compensation of saturating servomechanisms

OPTIMUM switching of second-order contactor servomechanisms has been treated in the literature. A method of approximating this performance without the use of relays or computers consists of substituting a particular type of network and a limiter for the computer and relays. A procedure is given for obtaining the characteristics of this network. It is illustrated by examples and experimental results. This type of linear compensation yields results that are better than those obtained by conventional linear compensation having uncontrolled saturation.
