چکیده    for linear time-invariant continuous-time singular systems, two new simple approaches, the kronecker method and the recursive method, are developed in order to estimate the states from the system input-output information via shifted legendre polynomials (slp) and a simple observer in the descriptor form. sufficient conditions for the existence of the present observer are given. the two methods simplify the system of state equations into the solution of a set of linear algebraic equations. furthermore, the proposed algorithms can be easily implemented in a digital computer and the solutions can be obtained for any length of time. further, these approaches include the filtering and the smoothing effect which can reduce the influence of zero-mean measurement noise on estimation. simulation results of a given numerical example demonstrate the effect of the proposed approaches.
