From 2D system to 1D system via restriction to a vertical strip: applications to time-controllability and zero-time-controllability
Aishwarya Bharti, Debasattam Pal
Motivated by the role of finite-time restriction in one-dimensional (1D) systems, we investigate the restriction of two-dimensional (2D) systems defined over to a ve…
Data-driven design of deadbeat observers for higher-order LTI systems
Aishwarya Bharti, Debasattam Pal
In this letter, we derive a necessary and sufficient condition for the existence of a deadbeat observer (DBO) for systems described by higher-order difference equations based on fi…
On unified asymmetric barrier Lyapunov functions
Susmitha T Rayabagi, Shashi Ranjan Kumar, Debasattam Pal +1
Barrier Lyapunov functions (BLFs) have been a popular choice when dealing with constrained control problems. In the current article, we present a unified asymmetric barrier Lyapuno…
Behavioral Inequalities
Soutrik Bandyopadhyay, Debasattam Pal, Shubhendu Bhasin
We introduce behavioral inequalities as a way to model dynamical systems defined by inequalities among their variables of interest. We claim that such a formulation enables the rep…
Designing Laplacian flows for opinion clustering in structurally balanced and unbalanced networks
Vishnudatta Thota, Twinkle Tripathy, Debasattam Pal
In this work, we consider a group of n agents whose interactions can be represented using unsigned or signed structurally balanced graphs or a special case of structurally unbalanc…
Optimal k-centers of a graph: a control-theoretic approach
Karim Shahbaz, Madhu N. Belur, Chayan Bhawal +1
In a network consisting of n nodes, our goal is to identify the most central k nodes with respect to the proposed definitions of centrality. Depending on the specific application,…
Asynchronous Distributed Consensus with Minimum Communication
Vishal Sawant, Debraj Chakraborty, Debasattam Pal
In this paper, the communication effort required in a multi-agent system (MAS) is minimized via an explicit optimization formulation. The paper considers a MAS of single-integrator…
Lattice All-Pass Filter based Precoder Adaptation for MIMO Wireless Channels
Parth Mehta, Agulla Surya Bharath, Kumar Appaiah +2
Modern 5G communication systems employ multiple-input multiple-output (MIMO) in conjunction with orthogonal frequency division multiplexing (OFDM) to enhance data rates, particular…
Design of Discrete-time Matrix All-Pass Filters Using Subspace Nevanlinna Pick Interpolation
Agulla Surya Bharath, Devanshu Singh Gaharwar, Kumar Appaiah +1
Unitary matrix-valued functions of frequency are matrix all-pass systems, since they preserve the norm of the input vector signals. Typically, such systems are represented and anal…
A matrix theoretic characterization of the strongly reachable subspace
Imrul Qais, Chayan Bhawal, Debasattam Pal
In this paper, we provide novel characterizations of the weakly unobservable and the strongly reachable subspaces corresponding to a given state-space system. These characterizatio…
The coarsest lattice that determines a discrete multidimensional system
Debasattam Pal, Shiva Shankar
A discrete multidimensional system is the set of solutions to a system of linear partial difference equations defined on the lattice . This paper shows that it is determined…
Stability Analysis for Fast Settling Switched DPLL
Pallavi Paliwal, Debasattam Pal, Shalabh Gupta
In current generation digital phase locked loop (DPLL) architectures, techniques like adaptive loop bandwidth with loop order switching and switched phase-detection are employed to…
Novel representation of discrete n-D autonomous systems
Debasattam Pal, Harish K. Pillai
In this paper we address the problem of representing solutions of a system of scalar linear partial difference equations akin to state space equations of 1-D systems theory. We fir…
Necessary condition on Lyapunov functions corresponding to the globally asymptotically stable equilibrium point
Chirayu D. Athalye, Harish K. Pillai, Debasattam Pal
It is well known that, the existence of a Lyapunov function is a sufficient condition for stability, asymptotic stability, or global asymptotic stability of an equilibrium point of…
