The linear state estimation for a class of singular systems is formulated by using the sequential linear estimator solution developed in steady state systems. This procedure is based upon sequential processing of the covariance of the estimate arising from the solution of the least squares problem. The convergence conditions of the state estimate are established. An application to state and input estimation in the dynamic discrete system is presented.
