ABSTRACT
The industry that deals with high pressure fluids use spherical tank for its storage purpose. The level control of such system is an important task. As the spherical tank is non-linear in nature, the conventional PID controller does not provide efficient control action. In this paper, the system behavior is analyzed in real time using PID controller and Integral-Proportional Derivative controller (I-PD). The I-PD controller, the diverse structure of conventional controller is considered and analyzed. The output responses of the proposed controller is obtained and the ouput shows that the I-PD controller gives best settling time and minimal peak overshoot value than the conventional PID controller.
