1.a. In a DC servo motor system, the tachometer feeds back a voltage that’s proportional to motor speed.Where does this voltage go to?A. The interpolator cardB. The CPU in the main controllerC. The driverD. The axis logic card1.b. A type of feedback device that uses a rotor and senses the position of the motor by means of sine andcosine waveforms is called a/anA. tachometer.B. encoder.C. resolver.D. alternator.

The act of controlling a final control element to change the manipulated variable to maintain the process variable at a desired set point is known as А. Controller Instrumentation C. Controlled variables D. Process control B.

In a control system, to simplify the block diagram in it is done block diagram reduction. Some of the methods are: cascade relationship, parallel connection, and feedback relationship. Explain the advantages and disadvantages of each method.
