A concise funnel robust model-free control mechanism for hypersonic space vehicles based on error driving

J. Syst. Control. Eng., 2021
Based on non-affine models of hypersonic space vehicles, the tracking control problem of hypersonic vehicles is studied and analyzed in this article using funnel robust model-free control mechanism considering parametric uncertainty and external ...

Electrostatic Funneling for Precise Nanoparticle Placement:  A Route to Wafer-Scale Integration

Nano Letters, 2007
We demonstrate a large-scale placement of nanoparticles through a scheme named "electrostatic funneling", in which charged nanoparticles are guided by an electrostatic potential energy gradient and placed on targeted locations with nanoscale precision. The guiding electrostatic structures are defined using current CMOS fabrication technology.

Funneling single photons into ridge-waveguide photonic integrated circuits

SPIE Proceedings, 2013
The generation, manipulation and detection of single photons enable quantum communication, simulation and potentially computing protocols. However scaling to several qubits requires the integration of these functionalities in a single chip. A promising approach to the integration of single-photon sources in a chip is the use of single quantum dots ...

Widely Wavelength-Tunable DFB Laser Array Integrated With Funnel Combiner

IEEE Journal of Selected Topics in Quantum Electronics, 2007
A wavelength-tunable distributed feedback (DFB) laser array integrated with a funnel combiner is described. Two types of optical combiner, namely a multimode interferometer (MMI) combiner and a funnel combiner, are compared theoretically and experimentally.

Fixed-Time Integral Terminal Sliding-Mode Control With Super-Twisting Nonlinear Extended-State Observer for Servo System With Disturbances

IEEE Journal of Emerging and Selected Topics in Industrial Electronics
In this article, a novel composite sliding-mode control (NCSMC) scheme is proposed for the servo system with disturbances. First, the funnel control is provided to constrain the output state, which can construct the system with some original system ...

Funnel-Based Online Recovery Control for Nonlinear Systems With Unknown Dynamics

arXiv.org
In this paper, we focus on recovery control of nonlinear systems from attacks or failures. The main challenges of this problem lie in (1) learning the unknown dynamics caused by attacks or failures with formal guarantees, and (2) finding the invariant ...
