Stability is one of the most important criteria in the field of automatic control. The most widely used control strategy in industries is the proportional integral derivative (PID) controller. PID controllers are popular as they can perform robustly in a wide range of operating conditions and due to their functional simplicity. In this work, PID controller's four modes of operation have been compared for providing optimum stability to a hydraulic level control system. It is shown that how P,
