Adaptive Robust H Control of Uncertain Linear Systems with State and Input Delay Mojtaba Hosseini Toodeshki todeshki@ec iut ac ir Date of Submission 2011 02 16 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree Ph D Language Farsi Supervisors Saeed Hosseinnia hoseinia@cc iut ac ir Javad Askari j askari@cc iut ac ir Ali Khaki Seddigh sedigh@kntu ac ir Advisor Isfahan University of Technology Khaje Nasir Toosi University of Technology Abstract In this thesis adaptive robust H control of uncertain systems with multiple delays in states and input is considered It is assumed that the parametric uncertainties are time varying norm bounded whose bounds are unknown and satisfy some matching conditions To overcome the effect of input delay and uncertainties a new Lyapunov Krasovskii functional with a new adaptive law have been introduced It is shown that the proposed adaptive robust controller guarantees asymptotic stability Also the controller has less number of design parameters and can be used for unstable systems For disturbance rejection two strategies are considered In the first approach disturbance should be norm bounded and satisfy the matching condition The second approach employs H method In this method it is assumed that the disturbance is a bounded energy signal All sufficient conditions are presented in LMI framework which can be easily solved by LMI toolbox in MATLAB For the simulation part two examples are considered River Pollution Control System is the first one with Biochemical Oxygen Demand BOD and Dissolved Oxygen DO as its states Another example is a numerical unstable system which has been considered in the previous papers Simulation results show the effectiveness of the proposed controller Keywords Uncertain time delay systems adaptive robust H control asymptotic stability input delay
