This introduces the proportional controller can be used for temperature control of any material or fluid. It means the dynamic characteristics of process will not get any disturbance even if there is no flow through the controller for small duration. A very important application of proportional controller with fixed bias or offset id the zero load process. Then transfer function of closed loop system with proportional controller is.

Now if u add Proportional controller to the system. By Comparing this with standard closed loop transfer function. Closed loop Transfer function of the system. The open loop transfer function is of above system is. The Proportional is used improve the transient response of the system. Transfer function of Proportional controller. Practical example of proportional controller. Further this automatic resetting is envisaged in controller concepts by adding integral controller to the proportional controller.

This is called manual resetting the controller to reduce the steady state error. This offset is changed manually by the operator for adjusting the controlled variable near to the set-point. This proportional offset also helps in bringing the controller variable near to the set-point which helps in reducing the error in steady state. What is 4 to 20mA Current, Voltage Calculation, ApplicationР”В¬onsider the above example of level controller, If the tank level reaches the set-point then valve will be closed by the controller and hence level raises again. Offset: In proportional controller, if the control variable reaches the set point then the deviation will become zero and hence the output valve which is multiplication of error will become zero. Relation between PB and Proportional Gain. This is ensure the level should not cross the band points in both sides. For example a hydraulic controller, to control the level of the tank with down stream valve. Normally this concept will be used in hydraulic controller and digital controller.

It also defined as the change in control variable that will drive the controller output for full scale. The resistor value can be changed to control the gain of the circuit and hence output of the system. Figure shows the electronic controller with gain element is resistor. The proportional gain is the percentage change of controller output related to percentage change in controller input. The setting of proportional constant can be expressed as. As the name specifies its output will be error deviation multiplied a factor electronic circuit gain Proportional controller can be used where the processing time of equipment or process is very large or where error magnitude is not needed to minimize to zero.
