Data-Driven Convex Approach to Off-road Navigation via Linear Transfer Operators
Joseph Moyalan, Yongxin Chen, Umesh Vaidya
We consider the problem of optimal navigation control design for navigation on off-road terrain. We use traversability measure to characterize the degree of difficulty of navigatio…
Information-Theoretic Approach for Model Reduction Over Finite Time Horizon
Punit Tulpule, Umesh Vaidya
This paper presents an information-theoretic approach for model reduction for finite time simulation. Although system models are typically used for simulation over a finite time, m…
Sparse Control Synthesis for Uncertain Responsive Loads with Stochastic Stability Guarantees
Sai Pushpak Nandanoori, Soumya Kundu, Jianming Lian +3
Recent studies have demonstrated the potential of flexible loads in providing frequency response services. However, uncertainty and variability in various weather-related and end-u…
A convex data-driven approach for nonlinear control synthesis
Hyungjin Choi, Umesh Vaidya, Yongxin Chen
We consider a class of nonlinear control synthesis problems where the underlying mathematical models are not explicitly known. We propose a data-driven approach to stabilize the sy…
Data-Driven Approach for Uncertainty Propagation and Reachability Analysis in Dynamical Systems
Amarsagar Reddy Ramapuram Matavalam, Umesh Vaidya, Venkataramana Ajjarapu
In this paper, we propose a data-driven approach for uncertainty propagation and reachability analysis in a dynamical system. The proposed approach relies on the linear lifting of…
Information Based Data-Driven Characterization of Stability and Influence in Power Systems
Subhrajit Sinha, Pranav Sharma, Venkataramana Ajjarapu +1
Stability analysis of a power network and its characterization (voltage or angle) is an important problem in the power system community. However, these problems are mostly studied…
Information Transfer in Dynamical Systems and Optimal Placement of Actuators and Sensors for Control of Non-equilibrium Dynamics

A Transfer Operator Methodology for Optimal Sensor Placement Accounting for Uncertainty
Himanshu Sharma, Umesh Vaidya, Baskar Ganapathysubramanian
Sensors in buildings are used for a wide variety of applications such as monitoring air quality, contaminants, indoor temperature, and relative humidity. These are used for accessi…
On Information Transfer Based Characterization of Power System Stability
Subhrajit Sinha, Pranav Sharma, Umesh Vaidya +1
In this paper, we present a novel approach to identify the generators and states responsible for the small-signal stability of power networks. To this end, the newly developed noti…
Transfer Operator Theoretic Framework for Monitoring Building Indoor Environment in Uncertain Operating Conditions
Himanshu Sharma, Anthony D. Fontanini, Umesh Vaidya +1
Dynamical system-based linear transfer Perron- Frobenius (P-F) operator framework is developed to address analysis and design problems in the building system. In particular, the pr…
Data-Driven Optimal Control Using Perron-Frobenius Operator
Apurba Kumar Das, Bowen Huang, Umesh Vaidya
In this paper, we propose a data-driven approach for control of nonlinear dynamical systems. The proposed data-driven approach relies on transfer Koopman and Perron-Frobenius (P-F)…
