Unbiased Extremum Seeking for MPPT in Photovoltaic Systems
Cemal Tugrul Yilmaz, Eric Foss, Mamadou Diagne +1
This paper presents novel extremum seeking (ES) strategies for maximum power point tracking (MPPT) in photovoltaic (PV) systems that ensure unbiased convergence and prescribed-time…
Unbiased Extremum Seeking for PDEs
Cemal Tugrul Yilmaz, Mamadou Diagne, Miroslav Krstic
There have been recent efforts that combine seemingly disparate methods, extremum seeking (ES) optimization and partial differential equation (PDE) backstepping, to address the pro…
Asymptotic, Exponential, and Prescribed-Time Unbiasing in Seeking of Time-Varying Extrema
Cemal Tugrul Yilmaz, Mamadou Diagne, Miroslav Krstic
Our recently developed "unbiased" extremum seeking (uES) algorithms ensure perfect convergence to the optimum at a user-assigned exponential rate or, more powerfully, within a user…
Perfect Tracking of Time-Varying Optimum by Extremum Seeking
Cemal Tugrul Yilmaz, Mamadou Diagne, Miroslav Krstic
This paper introduces extremum seeking (ES) algorithms designed to achieve perfect tracking of arbitrary time-varying extremum. In contrast to classical ES approaches that employ c…
Exponential and Prescribed-Time Extremum Seeking with Unbiased Convergence
Cemal Tugrul Yilmaz, Mamadou Diagne, Miroslav Krstic
We present multivariable extremum seeking (ES) designs that achieve unbiased convergence to the optimum. Two designs are introduced: one with exponential unbiased convergence (unbi…
