【Abstract】 Because all poles of a deadbeat observer are at the origin of coordinates, it has the character that the power of system matrix equals zero. Based on this character, we put forward a new method to design deadbeat observer for discrete linear systems in this paper. We can directly construct a deadbeat observer from I/O data without applying the technique of pole assignment. We give a detailed implementation procedure of the deadbeat observer. The correctness and validity is tested by simulation.更多还原
