A Low-Power Time-to-Digital Converter for the CMS Endcap Timing Layer (ETL) Upgrade
Wei Zhang, Hanhan Sun, Christopher Edwards +11
We present the design and test results of a Time-to-Digital-Converter (TDC). The TDC will be a part of the readout ASIC, called ETROC, to read out Low-Gain Avalanche Detectors (LGA…
On the Control Effort in Output Feedback Sliding Mode Control of Sampled-Data Systems
Thang Nguyen, Christopher Edwards, Vahid Azimi +1
In this paper, the problem of output feedback sliding mode control of linear sampled-data multi-input multi-output systems is considered. Existing sliding mode control schemes can…
Rapid Parameter Inference with Uncertainty Quantification for a Radiological Plume Source Identification Problem
Christopher Edwards, Ralph C Smith
In the event of a nuclear accident, or the detonation of a radiological dispersal device, quickly locating the source of the accident or blast is important for emergency response a…
Adaptive Super-Twisting Controller Design for Accurate Trajectory Tracking Performance of Unmanned Aerial Vehicles
D. M. K. K. Venkateswara Rao, Hamed Habibi, Jose Luis Sanchez-Lopez +3
In this paper, an adaptive super-twisting controller is designed for an agile maneuvering quadrotor unmanned aerial vehicle to achieve accurate trajectory tracking in the presence…
Secure State Estimation and Attack Reconstruction in Cyber-Physical Systems: Sliding Mode Observer Approach
Shamila Nateghi, Yuri Shtessel, Christopher Edwards +1
A cyber-physical system (CPS) is a tight coupling of computational resources, network communication, and physical processes. They are composed of a set of networked components, inc…
On the Behaviour of Under-tuned Super-Twisting Sliding Mode Control Loops
Dimitrios Papageorgiou, Christopher Edwards
This paper investigates the stability properties and performance of super-twisting sliding-mode control loops subject to periodic perturbations. Although there exist conditions on…
