Which of the following devices is used for conversion of co-ordinates?
Explanation: Synchro-Resolver is rotary transformer used for measuring degree of rotation and used for the conversion of the co-ordinates.
The effect of error damping is to
Explanation: Error damping is to reduce steady state error as it is used to enhance the steady state response of the system and this can be done by increasing the damping of the system.
______________technique gives quick transient and stability response
Explanation: Root locus is the right technique for the quick transient and stability response and gives the final response and quickly.
A phase lag lead network introduces in the output
Explanation: A phase lag lead network is the combination of the lead and lag network and also it lags at low frequencies and lead at high frequencies.
Which of the following is the non-linearity caused by servomotor?
Explanation: Linearity in the servo-motor is due to the saturation present and which is the important consideration for any type of the practical device.
___________can be extended to systems which are time-varying?
Explanation: State model representation is the best advantage for the systems over transfer function approach as it can be applied for the non-linear systems.
Laplace transform is used for the systems with:
Explanation: By definition of the transfer function by Laplace transform the initial conditions of the systems are considered to be zero.
Which of the following is an electromechanical device?
Explanation: LVDT is the electromechanical device which converts the displacement of the core to the electrical energy by the action of the transformer.
A differentiator is usually not a part of a control system because it
Explanation: A differentiator is generally not the part of the control system as it increases the input noise due to reduced gain and increased bandwidth.
If the gain of the critical damped system is increased it will behave as
Explanation: On increasing the gain damping will automatically get reduced and hence the oscillations in the system increases.
