Verified
A proportional controller:
A) is designed to eliminate the cycling associated with on/off control.
B) allows the final control element to take intermediate positions between on and off.
C) permits analog control of the final control element.
D) all of these.
Final Control Element
A device that directly manipulates a process variable to achieve a desired change, such as a valve or a motor.
Proportional Controller
A type of feedback controller that generates an output signal by multiplying the error between a desired setpoint and a measured process variable by a constant.
On/Off Control
A basic form of control used in various applications where the output is simply turned on or off, without intermediate states.
- Recognize the purposes of divergent control methods (PID, on/off, proportional, derivative, integral).

Final Answer :
D
Explanation :
A proportional controller eliminates cycling associated with on/off control, allows for intermediate positions between on and off, and permits analog control of the final control element. Therefore, all of these options are correct.
