According to 'Modern Control Engineering' written by Katsuhiko Ogata, the ratio fo the feedback signal, H(s)C(s)to the actuating error signal (R(s)-B(s)) is called the open-loop transfer function. Here, H(s) is the transfer function of the feedback signal detector, C(s) is the output signal and R(s) is the setpoint signal.
There is no range on a safety valve. It lifts and relieves at whatever it`s setpoint is. As for the setpoint, it would be just above the maximum working pressure/temperature of the water side of the boiler as stated on the National Board Tag of the vessel.
I believe it is: Loop condition Loop actions And how the loop breaks
A proportional-integral-derivative controller(PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
Negative feedback is the homeostatic mechanism that reduces any changes in the value of a variable or keeps a variable close to a pre-established setpoint. When the system detects a deviation from the setpoint, it initiates actions to bring the variable back to its desired level.

no.
no difference that's the difference
some feedback r insulting or inappropriate. it depend on how u sort the question. Question is on feed back system in control system. In a control system generally there is a setpoint to be achieved. Control system aims to achieve the setpoint. However due to inherent reasons, the actual keeps hovering around the setpoint. A good control system keeps the setpoint very close to the setpoint. Control system must know the actual value to make adjustment to achieve the setpoint. Actual value is fed back to the control system. This feed back is referred as negative or positive feedback. The feed back tells the control system that the actual value is lower or higher compared to set point. This is known as negative or positive feedback.
Differential Amplifier or Summing Amplifier are usually used in a closed loop control system. The error signal will be the DIFFERENCE between the setpoint value and feedback value for Differential Amplifier. Whereas for Summing Amplifier, the error signal will be the difference between the setpoint value and feedback value only if one of the value is inverted in polarity. Another reason Op Amp is used: amplify the error signal as error signals are usually very small. Hope this helps.

The term "close the loop" is a three part process: 1) recycle our waste, 2) make something new out of it, 3) buy recycled.

Well, sweetheart, a regulatory control system is like a strict parent that keeps things in line by maintaining a set value, while a servo system is more like a personal assistant that adjusts based on feedback to reach a desired position or speed. So basically, one plays by the rules, while the other is more flexible and adaptive. Hope that clears things up for you, pumpkin!
