Obstacle-Aware Online Receiver Planning in Multistatic Ranging
Jingwei Hu, Dave Zachariah, Petre Stoica +1
Multistatic ranging with mobile receivers enables good tracking performance due to the combined adaptive sensor geometry. However, environments that contain signal obstructing obst…
Detecting Feedback-path Delay Injection Attacks Using Interacting Multiple Model Filtering
Lovisa Eriksson, Torbjörn Wigren, Dave Zachariah +1
Time-delays are known to have a detrimental effect on feedback systems. In the context of networked cyber-physical systems, delays can be injected by malicious adversaries. Detecti…
Recursive Experiment Design for Closed-Loop Identification of ARMAX Systems with Output Perturbation Limits
Jingwei Hu, Dave Zachariah, Torbjörn Wigren +1
In many applications, system identification experiments must be performed in closed loop to ensure safety or to maintain system operation. In this paper, we consider the recursive…
Adaptive Experiment Design for Nonlinear System Identification with Operational Constraints
Jingwei Hu, Dave Zachariah, Torbjörn Wigren +1
We consider the joint problem of online experiment design and parameter estimation for identifying nonlinear system models, while adhering to system constraints. We utilize a reced…
Convergence in On-line Learning of Static and Dynamic Systems
Torbjörn Wigren, Ruoqi Zhang, Per Mattsson
The paper derives analytical expressions for the asymptotic average updating direction of the adaptive moment generation (ADAM) algorithm when applied to recursive identification o…
