control system

the deviation of the output of control system from desired response during steady state is called

• steady state error

• transient error

Transfer Function is Ratio of

• Laplace transform of input to the Laplace transform of output with all initial condition is zero

• Laplace transform of output to the Laplace transform of Input with all initial condition is zero

• Laplace transform of output to the Laplace transform of Input

• all of the above

In positive Feedback system,

• feedback signal in phase with Input signal

• feedback signal out of phase with input signal

• no relation between feedback signal and input signal

• none of the above

A system which is not having Feedback is called

• closed loop system

• open loop system

• both

• non of the above

What is the algebraic sum of the reference input and feedback?

• Error Signal
• Error Detector
• Controlled system
• Controlled output

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

A group of parts that work together to achieve a goal. 

• matter 
• system 
• conduction 
• solar energy 

This is information used to control the process or output of a system. 

• subsystems 
• input 
• feedback 
• banana 

How do u relate the DC motor speed?

• DC motor speed is directly proportional to armature voltage and inversely proportional to flux in field winding.

• DC motor speed is directly inversely proportional to armature voltage and inversely proportional to flux in field winding.

• DC motor speed is directly proportional to armature voltage and flux in field winding.

• DC motor speed is directly proportional to armature voltage and proportional to flux in field winding.
