Adaptive mixing control with multiple estimators
Baldi, S.; Ioannou, Petros A.; Kosmatopoulos, E. B. (2012)A recently proposed adaptive control scheme with mixing involves the use of precalculated candidate controllers whose output is weighted on the basis of the parameter estimates generated by an online parameter estimator. ...

Adaptive optimization for active queue management supporting TCP flows
Baldi, S.; Kosmatopoulos, E. B.; Pitsillides, Andreas; Lestas, Marios; Ioannou, Petros A.; Wan, Y. (Institute of Electrical and Electronics Engineers Inc., 2016)An adaptive decentralized strategy for active queue management of TCP flows over communication networks is presented. The proposed strategy solves locally, at each link, an optimal control problem, minimizing a cost composed ...

Convex design control for practical nonlinear systems
Baldi, S.; Michailidis, I.; Kosmatopoulos, E. B.; Papachristodoulou, A.; Ioannou, Petros A. (2014)This paper describes a new control scheme for approximately optimal control (AOC) of nonlinear systems, convex control design (ConvCD). The key idea of ConvCD is to transform the approximate optimal control problem into a ...

Evaluation of identifier based and & non-identifier based adaptive supervisory & control using a benchmark example
Baldi, S.; Ioannou, Petros A.; Mosca, E. (2010)Several classes of identifier and non-identifier based adaptive control schemes using a supervisory switching logic have been proposed in the literature. These schemes are based on different assumptions and claim to guarantee ...

A "plug and play" computationally efficient approach for control design of large-scale nonlinear systems using cosimulation: A combination of two "ingredients"
Baldi, S.; Michailidis, I.; Kosmatopoulos, E. B.; Ioannou, Petros A. (2014)As mathematical program-ming techniques and com-puter capabilities evolve, control designs are required to address control problems of ever-increasing scale and complexity. A particularly promising methodology toward such ...

A "plug-n-play" computationally efficient approach for control design of large-scale nonlinear systems using co-simulation
Baldi, S.; Michailidis, I.; Jula, H.; Kosmatopoulos, E. B.; Ioannou, Petros A. (Institute of Electrical and Electronics Engineers Inc., 2013)Recently, there has been a growing interest towards simulation-based control design (co-simulation), where the controller utilizes an optimizer to minimize or maximize an objective function (system performance) whose ...

Stability margins in adaptive mixing control via a Lyapunov-based switching criterion
Baldi, S.; Ioannou, Petros A. (2012)In all classes of linear adaptive control that involve switching or not there is no guarantee that after the switching stops or the adaptation is switched off the resulting closed loop linear time invariant system is stable ...
