In feedback measuring system
• indication is fedback via inverse transducer,
•compared with measurand and
•moves on to new steady state till error is reduced to zero.
Feedback control system controls relatively high power through actuator.
Feedback measuring system is drawing fairly low power devices at output (indicators, inverse transducer).
Feedback in measuring system•Improves accuracy in measurement
•Improves Speed of measurement
•Allows remote indication
•Allows noncontact measurement
BUT•Increases complexity of design, operation, size and cost
difference between feedback and control
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.
Their is no Difference
The three basic components of every feedback control system are: the sensor (or detector) which measures the system's output, the controller which processes this information and generates a control signal, and the actuator (or final control element) which takes the control signal and adjusts the system's input to achieve the desired output.
A dali is a unit used in lighting control systems to measure the digital addressability and control capability of individual light fixtures or devices. It allows for precise control and communication between lighting components in a system, enabling features such as dimming, color changing, and status feedback.
Define staregic control and financial control
Explain the difference between capability and control.
differentiate coordination and control
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.
I believe that servo is motorized and solenoid is magnetically activated.
Distinguish between internal audit and internal control.
