This paper attempts to develop an alternate but simple technique for designing a static Output feedback H, loop shaping controller front four-block H-infinity framework. Sufficient conditions are established for the existence of a static H-infinity loop shaping controller. These conditions are in LMI form and are different front those obtained in [Prempain. E.
