Stability of Slow-Fast Nonlinear Dynamics: Non-Periodic Case
G. Q. Bao Tran, Daniel Liberzon, Hyungbo Shim
We present sufficient conditions for the semi-global exponential stability of nonlinear systems whose dynamics have both slow and fast time variations. Unlike most existing results…
Inverse Learning-Based Output Feedback Control of Nonlinear Systems with Verifiable Guarantees
Yeongjun Jang, Hamin Chang, Heein Park +3
In this paper, we present a data-driven output feedback controller for nonlinear systems that achieves practical output regulation, using noise-free input/output measurement data.…
Blended Dynamics and Emergence in Open Quantum Networks
Qinghao Wen, Zihao Ren, Lei Wang +2
In this paper, we develop a blended dynamics framework for open quantum networks with diffusive couplings. The network consists of qubits interconnected through Hamiltonian couplin…
Adaptation of Parameters in Heterogeneous Multi-agent Systems
Hyungbo Shim, Jin Gyu Lee, B. D. O. Anderson
This paper proposes an adaptation mechanism for heterogeneous multi-agent systems to align the agents' internal parameters, based on enforced consensus through strong couplings. Un…
Determination of Bandwidth of Q-filter in Disturbance Observers to Guarantee Transient and Steady State Performance under Measurement Noise
Gaeun Kim, Hyungbo Shim
Q-filter-based disturbance observer (DOB) is one of the most widely used robust controller due to its design simplicity. Such simplicity arises from that reducing the time constant…
