ECE :: Automatic Control Systems
-
In control systems the output of sensor usually, is
-
Magnetic amplifier is used for
-
Assertion (A): In simplifying block diagram the product of transfer functions in feed forward direction must remain the same.
Reason (R): In simplifying block diagram the product of transfer functions around a closed loop must remain the same.
-
If block diagrams of the given figure (a) and (b) are to be equivalent, then
-
The pole zero plot in the given figure is for
-
The response to sinusoidal excitation can be found by
-
Assertion (A): Industrial robots improve productivity.
Reason (R): Robots can handle monotonous and complex jobs without error in operation.
-
The phase angle curve of G(jω) H(jω) is drawn by adding the phase angles of individual factors.
-
Consider the following statements about polar plots
- Addition of a non-zero pole to a transfer function results in further rotation of polar plot through an angle of - 90° as ω → ∞
- Addition of a pole at the origin to a transfer function rotates the polar plot at zero and infinite frequencies by a further angle of - 90°
