    © 2015 IOP Publishing Ltd. It is a significant challenge to reduce the scanning time in atomic force microscopy while retaining imaging quality. In this paper, a novel non-raster scanning method for high-speed imaging is ...
  • Adaptive repetitive control with feedforward scheme for grid-connected inverters 

    Abusara, M; Sharkh, S; Zanchetta, P (Institution of Engineering and Technology, 2015-08-01)
    This study is concerned with control of grid connected inverters using odd-harmonic repetitive scheme. Owing to the inherent long convergence period of repetitive control, a feedforward loop of the fundamental component ...
  • An adaptive sliding mode differentiator for actuator oscillatory failure case reconstruction 

    Alwi, Halim; Edwards, Christopher (Elsevier, 2013)
    This paper proposes an adaptive sliding mode super-twisting differentiator which allows the gains to adapt based on the ‘quality’ of the sliding motion. A Lyapunov based analysis for the adaptive super-twisting scheme is ...
