What is non touching loop?
Nontouching loops are such loops which have no common node, branch & path
What is marginally stable?
A system where the output comes neither finite nor infinite value but remains oscillates is called marginally stable
What is unstable system?
A system where output come towards the infinite value is known as an unstable system
What is stable system?
A system where the output come towards the finite value is calles as stable system
Classification of stability
Basically 3 type
1. Stable system
2.unstable system
3. Marginally stable
1. Stable system
2.unstable system
3. Marginally stable

Type of control system
Basically 2 type
1. The open-loop control system
2. The closed-loop control system
1. The open-loop control system
2. The closed-loop control system
Advantages of close loop control system
1. High bandwidth
2. The system is faster & more reliable
3.reduce effect of distortion & nonreliability
2. The system is faster & more reliable
3.reduce effect of distortion & nonreliability
Disadvantage of open loop control system
1.It is not reliable
2. System are very slow
3. Inaccurate result
2. System are very slow
3. Inaccurate result
Application of open loop control system
1. Automatic washing machine.
The automatic washing machine is a real-time application of an open-loop control system.
In automatic washing machine input is a dirty cloths & output is a clean cloth. Washing machine time set manually. After completion set time machine automatically stops. We may or may not get the desired clean cloths because of the no feedback from output to the input

Disadvantage of close loop control system
1. Complex & costlier system. 2. Bandwidth is high. 3 consume more power

Advantages of open loop control system
1. The open-loop system is simple in construction & design. 2. It is economical & easy to maintain & easy from a maintenance point of view
Close loop control system, Passive attack & Active attack
CLOSE LOOP CONTROL SYSTEM :
The control system in which the output has an effect upon the input quantity so as to maintain the desired output are called closed-loop control system
PASSIVE ATTACK :
In passive attack, Attacker observe the message without modification. Monitored the transmitted data & read the information. It does not make any change in data & the system. not disturbe the communication channel & neither affect information
