Abstract :
Considering the superiority of Divided Difference Filters (DDF) in state estimation of nonlinear systems versus conventional Extended Kalman Filter (EKF), DDF which are derivate-free Kalman filtering approach are exploited in state feedback control based on proportional integral (PI) controller. The proposed combination is applied to a Multi-Input Multi-Output three-tank system. The efficiency of the DDF algorithms in state estimation of the nonlinear system is reflected in the control law synthesized by the PI controller.
