Regulating the usage of hazardous chemicals in the manufacturing of medicines is critical in industries. Therefore it is required to regulate the level in the nonlinear tank and to avoid the wastage of chemicals used for its preparation. The research deals with the control of the level for a nonlinear hopper process tank. The main benefit of the hopper tank system is that it can able to store more quantity and also provides an easy flow of materials. To provide a better performance analysis, Fractional-Order PI (FOPI) is compared with the Particle Swarm Optimization method to optimize the PI controller parameters like Kp & Ki. The Optimized PI controller gain parameters provide the fastest settling time and reduce error using performance indices. The servo and regulatory responses were analyzed with different individual region-based control and combined region-based control of hopper tank system to achieve minimized settling time and minimized ISE, IAE & ITAE error values of process response.
