"WebbOne may see that there are issues with proportional control only. One of these issues is that proportional control cannot compensate for very small errors. (These errors are also known as offset.) Another issue is that it cannot adjust its output based on the rate of change in the measured variable. For example, if you are " - Theory proportional controller
