Abstract—The proportional integral derivative (PID) controller is the most widely used control strategy in industry. The popularity of PID controllers can be attributed partly to their robust performance in a wide range of operating conditions

In many industries process such as petro chemical industries, paper making industries and water treatment industries are using the tank system to control the liquid level. The liquid level must be controlled by the proper controller. The objectiv
