A method of designing the adaptive control system for the invariant closed-loop dominant conjugate complex poles has been developed by use of root-locus techniques. The method can be applied only to the controlled element containing one variable parameter varying with the surrounding conditions. However, it is also possible to apply it to the case where the transfer function of the controlled element is given in higher order rational function of s, whose coefficients change in large scale from the nominal values. Two subsidiary loops are required for the adaptation, one for phase adjustment, the other for gain adjustment. Each loop is composed of a nonlinear function generator incorporating the corresponding programming curve obtained graphically from root-locus and a servo which drives the adjustable controller.
