An Electronic Simulator for Nonlinear Servomechanisms

An electronic computer for the simulation of autopilot servomechanisms is being developed as a small-scale flexible analog computer capable of reproducing electrically the dynamic behavior of systems in which certain of the dependent variables or their derivatives may be limited in magnitude but which otherwise can be characterized by linear differential equations having constant coefficients. Specifically, the simulator is being designed to represent on a one-to-one time scale several types of closed-cycle systems or servomechanisms which are linear except for possible limitations of such quantities as motor torque, output velocity, and output displacement.
