Resilient Set-based State Estimation for Linear Time-Invariant Systems Using Zonotopes
Muhammad Umar B. Niazi, Amr Alanwar, Michelle S. Chong +1
This paper considers the problem of set-based state estimation for linear time-invariant (LTI) systems under time-varying sensor attacks. Provided that the LTI system is stable and…
Feedback Design for Devising Optimal Epidemic Control Policies
Muhammad Umar B. Niazi, Philip E. Paré, Karl H. Johansson
This paper proposes a feedback design that effectively copes with uncertainties for reliable epidemic monitoring and control. There are several optimization-based methods to estima…
Robust Data-Driven Predictive Control of Unknown Nonlinear Systems using Reachability Analysis
Mahsa Farjadnia, Amr Alanwar, Muhammad Umar B. Niazi +2
This work proposes a robust data-driven predictive control approach for unknown nonlinear systems in the presence of bounded process and measurement noise. Data-driven reachable se…
Secure State Estimation against Sparse Attacks on a Time-varying Set of Sensors
Zishuo Li, Muhammad Umar B. Niazi, Changxin Liu +2
This paper studies the problem of secure state estimation of a linear time-invariant (LTI) system with bounded noise in the presence of sparse attacks on an unknown, time-varying s…
Learning-based Design of Luenberger Observers for Autonomous Nonlinear Systems
Muhammad Umar B. Niazi, John Cao, Xudong Sun +2
Designing Luenberger observers for nonlinear systems involves the challenging task of transforming the state to an alternate coordinate system, possibly of higher dimensions, where…
Observer Design for the State Estimation of Epidemic Processes
Muhammad Umar B. Niazi, Karl Henrik Johansson
Although an appropriate choice of measured state variables may ensure observability, designing state observers for the state estimation of epidemic models remains a challenging tas…
Clustering-Based Average State Observer Design for Large-Scale Network Systems
Muhammad Umar B. Niazi, Xiaodong Cheng, Carlos Canudas-de-Wit +1
This paper addresses the aggregated monitoring problem for large-scale network systems with a few dedicated sensors. Full state estimation of such systems is often infeasible due t…
