OPTIMUM ADJUSTMENT OF A TORQUE-SATURATED SERVOMECHANISM
Abstract
An analysis is presented of the behavior of a saturated system characterized by inertia and friction. Investigation was directed towards problems of loss in transient response as a result of saturation and the design of a system making the best use of saturation. A comparison of optimum saturated servomechanisms with optimum relay servomechanisms is also included. An idealized saturation curve was assumed, and the step function response was computed. The integrals of the absolute and squared error were determined and employed in assessing the importance of saturation. The study indicated that an optimum damping ratio exists which decreases with the size of the step input; that the system gain in the unsaturated region can be increased to advantage; and that performance of the saturating system is similar to that of an optimum off-on system for large inputs, but is inferior for small inputs.
