Describe and compare the characteristics of (a) proportional control, (b) proportional plus integral control, (c) proportional p
stira [4]

Answer:

The answer is below

Explanation:

1. Proportional Control is a form of control engineering in which an output is directly proportional to the error signal.

Characteristics of proportional control are:

* It is utilized when the deviation between the input and output is small

* It is also utilized when the deviation is not sudden.

* It reduces steady-state error

* It speeds up the response of the overdamped system

2. Proportional plus Integral Control is a form of control engineering in which a collective proportion and integral control of the output is equivalent to the combined proportion and integral of the error signal.

Characteristics of proportional plus integral control are:

* it can revert the controlled variable to the original set point

* It decreases steady-state error

* It quickens up the reaction of the overdamped system

3. Proportional plus integral plus derivative control is mostly applicable in operating the process elements such as temperature, pressure, speed, etc. It is recommended for industrial use.

Characteristics of Proportional plus integral plus derivative control are:

* It enhances the temporary reaction of the system.

* It also lessens steady-state error

* It accelerates the response of the overdamped system

Consider steady heat transfer through the wall of a room in winter. The convection heat transfer coefficient at the outer surfac
AveGali [126]

The heat transfer which is in steady state, the heat transfer rate to the wall is equal to the wall.

<u>Explanation:</u>

  • The convection transfer of heat to the wall is

         Q=h A\left(T_{s}-T_{f}\right)

  • Here, T_{S} is the temperature of solid surface, T_{f} is the temperature of moving fluid stream which is adjacent of solid surface, h is the heat transfer coefficient.
  • The coefficient of convection heat transfers outer surface contains 3 times to the inner surface which experience smaller drop of temperature for 3 times that compares to inner surface.
  • Hence, the temperatures outer surface get close to the surroundings of air temperature.
