Periodic Event-triggered Control for Incrementally Quadratic Nonlinear Systems
Xiangru Xu, Adam M. Tahir, Behcet Acikmese
Periodic event-triggered control (PETC) evaluates the triggering rule periodically and is well-suited for implementation on digital platforms. This paper investigates PETC design f…
Passivity-Based Analysis of Sampled and Quantized Control Implementations
Xiangru Xu, Necmiye Ozay, Vijay Gupta
This paper studies the performance of a continuous controller when implemented on digital devices via sampling and quantization, by leveraging passivity analysis. Degradation of pa…
Approximation of The Constrained Joint Spectral Radius via Algebraic Lifting
Xiangru Xu, Behcet Acikmese
This paper studies the constrained switching (linear) system which is a discrete-time switched linear system whose switching sequences are constrained by a deterministic finite aut…
Successive Convexification: A Superlinearly Convergent Algorithm for Non-convex Optimal Control Problems
Yuanqi Mao, Michael Szmuk, Xiangru Xu +1
This paper presents the SCvx algorithm, a successive convexification algorithm designed to solve non-convex constrained optimal control problems with global convergence and superli…
Observer-Based Controllers for Incrementally Quadratic Nonlinear Systems with Disturbances
Xiangru Xu, Behcet Acikmese, Martin J. Corless
Robust global stabilization of nonlinear systems by observer-based feedback controllers is a challenging task. This article investigates the problem of designing observer-based sta…
