Zakwan, MuhammadAhmed, SaeedBajcinca, Naim2020-12-162020-12-162020-12-16202110.1002/rnc.5343https://infoscience.epfl.ch/handle/20.500.14299/174095WOS:000595094800001This article proposes a new clock-dependent gain-scheduled dynamic output feedback controller for delayed linear parameter varying systems with piecewise constant parameters. The proposed controller guarantees Script capital L2-performance. By employing a clock-dependent Lyapunov-Krasovskii functional, a sufficient condition for the existence of the controller is provided in terms of clock- and parameter-dependent linear matrix inequalities. A case study on output feedback control of delayed switched systems is also provided. To illustrate the efficacy of the result, it is applied to a practical VTOL helicopter model.Automation & Control SystemsEngineering, Electrical & ElectronicMathematics, AppliedAutomation & Control SystemsEngineeringMathematicslpv systemsoutput feedbackh-infinity controlstability analysisL2 output feedback control of delayed linear parameter varying systems with piecewise constant parameters: A clock-dependent L-K approachtext::journal::journal article::research article
