Precision controller for rotating choppers
A dc motor electronic controller, driving a rotating chopper, is presented. The controller uses an integral feedback technique, consisting of charging a storage capacitor by means of width modulated pulses. These pulses are obtained by comparing the revolution time of the chopper with a fixed time....

| description | A dc motor electronic controller, driving a rotating chopper, is presented. The controller uses an integral feedback technique, consisting of charging a storage capacitor by means of width modulated pulses. These pulses are obtained by comparing the revolution time of the chopper with a fixed time. It is shown that the steady‐state angular speed is independent both of the friction coefficient and the feedback loop gain. The stability condition of the feedback loop gain is also derived. |
