Nonlinear process control is an important tool in process industry. In this work the authors have proposed a nonlinear model-based control scheme. The paper examines the servo and regulatory responses of the proposed approach. Extensive simulation results demonstrate that the controller provides improved performance compared to conventional PI schemes, while effectively reducing measurement noise and enhancing robustness.

Conclusion
From the extensive simulation study, it can be concluded that the servo and regulatory performances of the proposed control schemes applied to the spherical tank process are satisfactory. Comparative analysis indicates that the proposed schemes achieve faster settling times than the CA-PI controller during set-point variations. It is also observed that the proposed schemes eliminate disturbances more quickly compared to the CA-PI control scheme. Furthermore, the CA- PI controller exhibits poorer robustness in comparison to the proposed approaches. The proposed control schemes are also more effective in reducing measurement noise than the CA-PI controller. Overall, based on performance evaluation, the proposed control schemes outperform the CA-PI control strategy.
