On input-output persistency and the interconnection of positive nonlinear systems
Arthut Castello B. de Oliveira, Moh K. Wafi, Eduardo D. Sontag
In this paper we study feedback interconnections of positive nonlinear SISO systems and introduce two complementary properties: persistent-input/persistent-output (PIPO) for the pl…
Distributed Adaptive Estimation of Unknown Nonlinear Systems without Input Sharing
Moh Kamalul Wafi, Milad Siami
This paper studies distributed adaptive state estimation for discrete-time nonlinear systems with unknown source dynamics over directed communication networks. Each sensing agent e…
Neural-Enhanced Micro-Kalman Filtering for Satellite Tracking: A Comparative Study
Moh Kamalul Wafi
Satellite state estimation plays a fundamental role in orbital navigation, tracking, and autonomous space operations. Accurate estimation remains challenging due to uncertainties i…
On the Comparison of Reinforcement Learning and Adaptive Control for Linear Systems under Packet Loss and Uncertainty
Moh Kamalul Wafi
This paper presents a comparative study between Adaptive Quantized Control (AQC) and Deep Deterministic Policy Gradient (DDPG) reinforcement learning for uncertain linear systems w…
Boundedness of solutions in feedback systems with antithetic controllers
Moh Kamalul Wafi, Arthur C. B. de Oliveira, Eduardo D. Sontag
Antithetic feedback controllers have become a key experimental and theoretical tool in synthetic biology. Introduced by Khammash and collaborators about 10 years ago, they are empl…
Adaptive Covariance Kalman Filtering and Nonlinear Decoupling Control via Feedback Linearization for a Three-Tank Process
Bambang L. Widjiantoro, Katherin Indriawati, Moh Kamalul Wafi
Hydraulic three-tank systems are widely used in water treatment and liquid storage applications, where accurate level regulation is essential for safe and efficient operation. This…
