Deadbeat control of discrete-time systems using output feedback

摘要: An nth-order closed-loop discrete-time system is said to exhibit a deadbeat response if any arbitrary initial state taken the origin in n steps. This paper studies problem of obtaining for by means constant output feedback and establishes condition existence dead-beat controller. obtained directly from restrictions on attainable poles when employed. When satisfied, required matrix exists calculated relationship given paper. The first solved single-input systems result then extended multivariable systems, where matrices used are restricted having unity rank. Deadbeat control unrestricted also discussed. A number illustrative numerical examples given.
