Automatic Control Systems Satisfying Certain General Criteria on Transient Behavior

An analytic method for the design of automatic controls has been developed by these authors. The method starts from certain arbitrary criteria on the behavior of the controlled system. It then gives those physically realizable equations that the control system can follow in order to realize this behavior. The criteria used are developed in the form of certain time integrals.

General results are shown for systems of second order and of any number of degrees of freedom. Detailed examples for several cases in the control of a turbojet engine are presented.
