Interpolation Conditions for Instant Data Consistency with Port-Hamiltonian Structure
Martina Vanelli, Nima Monshizadeh, Julien M. Hendrickx
We develop a data-driven framework for nonlinear port-Hamiltonian (pH) systems based on interpolation conditions to characterize consistency between observed data and structured dy…
Distributed Stability Certification and Control from Local Data
Surya Malladi, Nima Monshizadeh
Most data-driven analysis and control methods rely on centralized access to system measurements. In contrast, we consider a setting in which the measurements are distributed across…
Privacy-preserving cloud computation of algebraic Riccati equations
Venkata Surya Prakash Malladi, Nima Monshizadeh
We address the problem of securely outsourcing the solution of algebraic Riccati equations (ARE) to a cloud. Our proposed method explores a middle ground between privacy preserving…
Dynamic interventions with limited knowledge in network games
Mehran Shakarami, Ashish Cherukuri, Nima Monshizadeh
This paper studies the problem of intervention design for steering the actions of noncooperative players in quadratic network games to the social optimum. The players choose their…
Diagonal Stability of Systems with Rank-1 Interconnections and Application to Automatic Generation Control in Power Systems
John W. Simpson-Porco, Nima Monshizadeh
We study a class of matrices with a rank-1 interconnection structure, and derive a simple necessary and sufficient condition for diagonal stability. The underlying Lyapunov functio…
Optimal intervention strategies to mitigate the COVID-19 pandemic effects
Andreas Kasis, Stelios Timotheou, Nima Monshizadeh +1
Governments across the world are currently facing the task of selecting suitable intervention strategies to cope with the effects of the COVID-19 pandemic. This is a highly challen…
Steering the aggregative behavior of noncooperative agents: a nudge framework
Mehran Shakarami, Ashish Cherukuri, Nima Monshizadeh
This paper considers the problem of steering the aggregative behavior of a population of noncooperative price-taking agents towards a desired behavior. Different from conventional…
Privacy and Robustness Guarantees in Distributed Dynamics for Aggregative Games
Mehran Shakarami, Claudio De Persis, Nima Monshizadeh
This paper considers the problem of Nash equilibrium (NE) seeking in aggregative games, where the payoff function of each player depends on an aggregate of all players' actions. We…
Quadratic Performance Analysis of Secondary Frequency Controllers
Bala Kameshwar Poolla, John W. Simpson-Porco, Nima Monshizadeh +1
This paper investigates the input-output performance of secondary frequency controllers through the control-theoretic notion of norms. We consider a quadratic objective accou…
Primary frequency regulation in power grids with on-off loads: chattering, limit cycles and convergence to optimality
Andreas Kasis, Nima Monshizadeh, Ioannis Lestas
Load side participation can provide valuable support to the power network in case of urgencies. On many occasions, loads are naturally represented by on and off states. However, th…
A distributed scheme for secondary frequency control with stability guarantees and optimal power allocation
Andreas Kasis, Nima Monshizadeh, Ioannis Lestas
We consider the problem of distributed secondary frequency regulation in power networks such that stability and an optimal power allocation are attained. This is a problem that has…
A feedback control algorithm to steer networks to a Cournot-Nash equilibrium
Claudio De Persis, Nima Monshizadeh
We propose a distributed feedback control that steers a dynamical network to a prescribed equilibrium corresponding to the so-called Cournot-Nash equilibrium. The network dynamics…
Secant and Popov-like Conditions in Power Network Stability
Nima Monshizadeh, Ioannis Lestas
The problem of decentralized frequency control in power networks has received an increasing attention in recent years due to its significance in modern power systems and smart grid…
