Abstract : A general longitudinal feedback control system containing pitch, pitch rate, depth, and depth rate feedback is described. The Laplace domain transfer functions for each feedback loop are developed. A computer analysis program using the root locus technique is developed for aiding in the design of the control system. An illustrative example design problem is included.
