Abstract
This paper presents the modeling of a hydraulic proportional circuit and sets up the discrete state-space model. Aiming at the nonlinear model, the extended Kalman filter (EKF) algorithm is introduce here. The application of EKF towards the state estimation of the discrete state-space model is present in the last.
