Following results are obtained by our Internet Research Algorithm: Lets understand the feed forward control with an example, Suppose there is a system in which we are making steam from water so here water act as a input and steam act as a output. So, when you take a reading from the output or we can say that after the whole process than it is called feedback control and then you can make changes for obtaining desired values in input. But, when we take readings before the output with the help of sensors or other mediums than it is called feed forward control or predictive control.
