Abstract :
In this note, a technique is presented for the estimation with unknown inputs. This technique is based on transforming a standard system with unkown inputs into a singular system by an orthogonal transformation. Then, the results of state estimation of singular systems can be applied to estimate the state and inputs. Conditions of the convergence and stability of the obtained estimate are given.
