Q. (A): Signal flow graphs can be used for block diagram reduction of linear control system.
(B): Signal flow graph is a graphical representation for the variables representing the outputs of the various blocks of the control system.
Q. (A): Tachogenerator feedback is used as minor loop feedback in position control systems to improve stability.
(B): Tachogenerator provides velocity feedback which decreases the damping in the system.
Q. (A): The state transition matrix represents the free response of the system.
(B): The state transition matrix satisfies the homogeneous state equation.
Q. (A): If the impulse response of a network is available, the response to any arbitrary input can be derived.
(B): The laplace transform of unit impulse is unity.
Q. (A): Process industry applications should ideally be tuned for critical damping.
(B): Critically damped response has no oscillations in the output.
