Feed Forward Control in Heat Exchanger

Feedforward control is a control strategy where the control action is taken based on the anticipated future behavior of the system, rather than just its current behavior. In this approach, the control action is taken based on the predicted future output of the system, based on the input signal.
An example of feedforward control in a heat exchanger can be as follows:
Let's consider a heat exchanger system, where the input temperature is constantly changing, and the output temperature needs to be maintained at a constant value. In this case, the feedforward control strategy can be used to predict the future output temperature based on the current input temperature, and adjust the control action accordingly. For example, if the input temperature is increasing, the control action can be to increase the flow of coolant, thus compensating for the increase in input temperature, and maintaining the output temperature at the desired value.
In conclusion, feedforward control provides improved performance compared to feedback control in systems where the future behavior of the system can be predicted based on the input signal.
