Many varied methods can be used to compensate a control system, This paper is a study of the effects of using the motor input voltage as a feedback quantity. It uses a unity feedback positioning system servo-mechanism as the uncompensated system and investigates the effect on root location with the motor input voltage fed back through various compensating devices, such as a lag or lead network. Only type zero and type one systems are considered. These vary from second order to fourth order. Root loci approach is used with some of the systems checked on the analog computer.
