Kalman Filter and its Application on Tuning PI Controller Parameters

This work addresses EKF and UKF tuning logic based PI Control algorithm implemented on standard nonlinear process. A typical CSTR process was chosen to demonstrate the practical utility and effectiveness of the proposed tuning methods. Both servo and regulatory performance even in presence of observational noise using the tuning methodologies were found satisfactory. The performances of the proposed PI techniques have been analyzed and compared with traditional adaptive PI (TA-PI) control law. From the extensive simulation studies, it was observed that the proposed techniques implemented on CSTR process for temperature controlling are having better performance over TA-PI control scheme. It was also investigated that developed schemes exhibit achievable robust performances.
