Abstract
In many chemical engineering applications the extended Kalman filter (EKF) is often used to deal with certain classes of nonlinear systems. This paper compares basic and polynomial approach of EKF for parameters estimation of nonlinear continuous-time stochastic systems. The proposed approaches are used to estimate constants k11 and k22 for interacting tank-in-series process and frequency factor k0 and temperature of reaction mixture theta for continuous stirred-tank reactor (CSTR).
