Via basic and descriptor adverse transformation of matrix, an equivalent standard linear system is derived. Sufficient and necessary conditions are established for observers with disturbance decoupling and LTR in systems. Analysis showed that the necessary and sufficient condition for observers with LTR is disturbance decoupling to any undnown inputs. So it is con verted to the problem that observers are designed with disturbance decoupling.
