Abstract :
In this paper a simple unknown inputs estimation method for linear time invariant systems is proposed. Reduced order unknown input Das and Ghosal observer is extended and used for this purpose. Required conditions are derived for existence of such estimator. Numerical examples with MATLAB simulation results are given to illustrate the proposed scheme.
