ROBUST CONTROL OF UNCERTAIN LINEAR SYSTEM WITH DISK POLE CONSTRAINTS

摘要: For a class of uncertain linear systems, necessary and sufficient condition for the existence state feedback control laws which assign closed loop poles in prespecified disk is derived terms matrix inequalityies(LMIs). The problem designing controllers with smaller gain parameters formulated as convex programme LMI constrains, can be solved by existing software. proposed method applicable to both continuous discrete time systems.
