Ahmed, S.Özbay, Hitay2018-04-122018-04-1220162405-8963http://hdl.handle.net/11693/36827A control algorithm based on switching robust controllers is presented for a Linear Parameter Varying (LPV) time-delay system modeling automatic infusion of vasodilator drug to regulate postsurgical hypertension. The system is scheduled along a measurable signal trajectory. The prospective controllers are robustly designed at various operating points forming a finite set of robust controllers and then a hysteresis switching is performed between neighboring robust controllers for a larger operating range of the LPV system. The stability of the switching LPV system for the entire operating range is ensured by providing a sufficient condition in terms of bound on the scheduling signal variation using the concept of dwell time. Simulation results are provided to verify the performance of the designed control scheme. © 2016EnglishBiomedical control systemHysteresis switchingLife sciencesLPV systemRobust controlTime-delay systemUncertain systemBlood pressureDelay control systemsHysteresisRobust controlSwitchingTime delayUncertain systemsBiomedical controlHysteresis switchingLife-sciencesLPV systemsTime-delay systemsControllersArticle10.1016/j.ifacol.2016.07.538
