State and parameter estimation of CSTR using joint-UKF
In many of nonlinear chemical processes, EKF algorithm has been widely used. This algorithm is not suitable for severe nonlinear dynamics. Recently UKF is preferred. UKF has more accurate approximation, but still is not suitable for time varying dynamics. To overcome this deficiency, a nonlinear joint (state and parameter) estimation algorithm based UKF is presented, which is called as Joint-UKF. Joint-UKF, Dual-EKF, Joint-UKF are applied to a CSTR with cooling jacket in which the production of propylene glycol happens and the results of simulation are evaluated.
