Resilient Extremum Seeking Control for Cyber-Physical Systems Under Denial-of-Service Attacks
Filipe da Silva Bastos Teixeira, Pedro Henrique Silva Coutinho, Tiago Roux Oliveira +1
Extremum seeking control (ESC) relies on deliberately injected excitation to extract optimization information from measured outputs, making its networked implementation particularl…
Towards Co-Designed Event-Triggered Extremum Seeking
Roberto Luo, Pedro Henrique Silva Coutinho, Victor Hugo Pereira Rodrigues +2
This paper studies event-triggered gradient-based multivariable extremum seeking for nonlinear maps with polytopic Hessian uncertainty. Unlike existing event-triggered extremum-see…
Extremum Seeking Control for Wave-PDE Actuation with Distributed Effects
Elisio Juvenal Muchave, Pedro Henrique Silva Coutinho, Tiago Roux Oliveira +1
This paper deals with the gradient-based extremum seeking control (ESC) with actuation dynamics governed by distributed wave partial differential equations (PDEs). To achieve the c…
Multivariable Gradient-Based Extremum Seeking Control with Saturation Constraints
Enzo Ferreira Tomaz Silva, Pedro Henrique Silva Coutinho, Tiago Roux Oliveira +2
