Hybrid Energy Storage Implementation In Dc And Ac Power System For Efficiency, Power Quality And Reliability Improvements, Mustafa Farhadi
Hybrid Energy Storage Implementation In Dc And Ac Power System For Efficiency, Power Quality And Reliability Improvements, Mustafa Farhadi
FIU Electronic Theses and Dissertations
Battery storage devices have been widely utilized for different applications. However, for high power applications, battery storage systems come with several challenges, such as the thermal issue, low power density, low life span and high cost. Compared with batteries, supercapacitors have a lower energy density but their power density is very high, and they offer higher cyclic life and efficiency even during fast charge and discharge processes. In this dissertation, new techniques for the control and energy management of the hybrid battery-supercapacitor storage system are developed to improve the performance of the system in terms of efficiency, power quality and …
Lyapunov-Based Robust And Adaptive Control Design For Nonlinear Uncertain Systems, Kun Zhang
Lyapunov-Based Robust And Adaptive Control Design For Nonlinear Uncertain Systems, Kun Zhang
Electronic Theses and Dissertations
The control of systems with uncertain nonlinear dynamics is an important field of control science attracting decades of focus. In this dissertation, four different control strategies are presented using sliding mode control, adaptive control, dynamic compensation, and neural network for a nonlinear aeroelastic system with bounded uncertainties and external disturbance. In Chapter 2, partial state feedback adaptive control designs are proposed for two different aeroelastic systems operating in unsteady flow. In Chapter 3, a continuous robust control design is proposed for a class of single input and single output system with uncertainties. An aeroelastic system with a trailingedge flap as …
