Distributed Optimization via Energy Conservation Laws in Dilated Coordinates
Kushal Chakrabarti, Mayank Baranwal
Continuous-time models can reveal accelerated structures in distributed optimization, but their rates need not survive direct discretization. We introduce a second-order primal--du…
On Convergence of the Iteratively Preconditioned Gradient-Descent (IPG) Observer
Kushal Chakrabarti, Nikhil Chopra
This paper considers the observer design problem for discrete-time nonlinear dynamical systems with sampled measurement data. Earlier, the recently proposed Iteratively Preconditio…
On Linear Convergence of PI Consensus Algorithm under the Restricted Secant Inequality
Kushal Chakrabarti, Mayank Baranwal
This paper considers solving distributed optimization problems in peer-to-peer multi-agent networks. The network is synchronous and connected. By using the proportional-integral (P…
Iteratively Preconditioned Gradient-Descent Approach for Moving Horizon Estimation Problems
Tianchen Liu, Kushal Chakrabarti, Nikhil Chopra
Moving horizon estimation (MHE) is a widely studied state estimation approach in several practical applications. In the MHE problem, the state estimates are obtained via the soluti…
