Kalman estimator for an Active Suspension System

Kalman estimator is designed to estimate the unmeasurable system states in an Active Suspension System (ASS) in two modes. In the first mode, the estimated road input is given to the estimator to estimate the state variables. In the second mode, the actual road input is given to the estimator to estimate the state variables. In both the modes, the estimated state variables are compared with actual state variables. From the simulation results, it is concluded that the estimated state variables using Kalman estimator with the actual road input is very close to actual state variables even in the presence of measurement noise.
