This paper describes about the level control of conical tank by using PID control and fuzzy logic algorithm. Many process industries are equipped with conical tanks because of easy discharge of contents present in it. But level control in the conical tank is most challenging parameter which is to be monitored. This non-linearity can be overcome by different controlling techniques. Conventionally used controller in most of the industries is PID controller. Further the controller is updated with fuzzy logic controller for the enhanced response regarding level control. A result of fuzzy logic controller is compared with conventional PID to analyze the performance in terms of high stability, reliability and robustness.

In this paper, a robust setpoint tracking disturbance rejection and aggressiveness (RTD-A) controller is designed and developed to control the liquid level of a conical tank process. Meta-heuristic algorithms like grey wolf optimization and the genetic algorithm are used to tune the parameters of the RTD-A controller. Its performance is later compared with that of the conventional standard proportional integral derivative controller. The gain scheduled RTD-A controller is designed and implemented on a nonlinear conical tank process. Also, various performances attributes such as the integral square error, integral absolute error, integral time absolute error, rise time, and settling time are calculated for the first-order process and conical tank process. The servo responses with RTD-A are also compared against the responses recorded from the conventional control schemes.
