This　paper　presents　a　hybrid　static　output　feedback　stabilization　approach　for　harmonic　oscillating　systems,　which　are　not　stabilized　via　a　single　static　output　feedback.　More　precisely,　we　find　two　output　feedback　control　gains　and　a　switching　law　orchestrating　the　feedback　gains　such　that　the　deduced　closed-loop　switched　system　is　asymptotically　stable.　Based　on　a　new　sufficient　condition　for　stabilization　of　second-order　switched　linear　systems,　under　the　predetermined　＇most　stabilizing＇　switching　law　which　is　a　time-controlled　switching,　it　is　shown　that　stability　conditions　can　be　met　with　respect　to　the　discrete　state　when　the　switched　system＇s　stabilization　theorem　is　used.　Copyright　©　2006　SoftMotor　Ltd.
