Observability and State Estimation for Smooth and Nonsmooth Differential Algebraic Equation Systems
Hesham Abdelfattah, Sameh A. Eisa, Peter Stechlinski
In this work, we extend the sensitivity-based rank condition (SERC) test for local observability to another class of systems, namely smooth and nonsmooth differential-algebraic equ…

Extremum Seeking with High-Order Lie Bracket Approximations: Achieving Exponential Decay Rate
Victoria Grushkovskaya, Sameh A. Eisa
This paper focuses on the further development of the Lie bracket approximation approach for extremum seeking systems. Classical results in this area provide extremum seeking algori…

A New Nonsmooth Optimal Control Framework for Wind Turbine Power Systems
Hesham Abdelfattah, Sameh A. Eisa, Peter Stechlinski
Optimal control theory extending from the calculus of variations has not been used to study the wind turbine power system (WTPS) control problem, which aims at achieving two target…
