Sparsity in control problems: Recent trends and open challenges
Luca Ballotta, Geethu Joseph, Geethu Josephb +7
As in all fields of engineering, control engineers constantly face a dichotomy between achieving high performance and the limited availability of resources for sensing, actuation,…
Adaptive Stepsizes With Certified Convergence in Distributed Gradient Tracking With Quadratic Costs
Yifan Wang, Luca Ballotta, Ruggero Carli +3
In this work, we propose an adaptive stepsize rule with guaranteed convergence for Distributed Gradient Tracking applied to scalar quadratic problems with heterogeneous curvatures.…
Pursuing Optimal Stepsize in Adaptive Gradient-Based Quadratic Optimization
Yifan Wang, Luca Ballotta, Ruggero Carli +2
In this paper, we address the problem of achieving fast convergence in gradient descent for quadratic functions without relying on a priori knowledge of global function parameters.…
The role of communication delays in the optimal control of spatially invariant systems
Luca Ballotta, Juncal Arbelaiz, Vijay Gupta +2
We study optimal proportional feedback controllers for spatially invariant systems when the controller has access to delayed state measurements received from different spatial loca…
Faster Consensus via a Sparser Controller
Luca Ballotta, Vijay Gupta
In this paper, we investigate the architecture of an optimal controller that maximizes the convergence speed of a consensus protocol with single-integrator dynamics. Under the assu…
Can Decentralized Control Outperform Centralized? The Role of Communication Latency
Luca Ballotta, Mihailo R. Jovanović, Luca Schenato
In this paper, we examine the influence of communication latency on performance of networked control systems. Even though distributed control architectures offer advantages in term…
From Sensor to Processing Networks: Optimal Estimation with Computation and Communication Latency
Luca Ballotta, Luca Schenato, Luca Carlone
This paper investigates the use of a networked system (, swarm of robots, smart grid, sensor network) to monitor a time-varying phenomenon of interest in the presence of comm…
Computation-Communication Trade-offs and Sensor Selection in Real-time Estimation for Processing Networks
Luca Ballotta, Luca Schenato, Luca Carlone
Recent advances in electronics are enabling substantial processing to be performed at each node (robots, sensors) of a networked system. Local processing enables data compression a…
