A new estimation of the lower error bound in balanced truncation method
(2014-08-01)
Article
Accés obertFor a single-input/single-output (SISO) linear time-invariant dynamical system, the standard H-infinity-norm lower error bound of balanced truncation method is parallel to G(s) - G(r)(s)parallel to(H infinity) >= sigma(r+1), ... -
A sliding mode control for a wound rotor synchronous generator with an isolated RL load
(IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Comunicació de congrés
Accés obertIn this paper a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive ... -
A sliding mode controlled three wheeled narrow vehicle
(2013)
Article
Accés restringit per política de l'editorialThis paper presents a sliding mode controller for a narrow tilting three-wheeled vehicle. The vehicle is modelled as a dynamic eighteen-order system with two inputs and two outputs, however, a simple third-order model of ... -
A unified approach to explain contrary effects of hysteresis and smoothing in nonsmooth systems
(2017-09-01)
Article
Accés obertPiecewise smooth dynamical systems make use of discontinuities to model switching between regions of smooth evolution. This introduces an ambiguity in prescribing dynamics at the discontinuity: should the dynamics be given ... -
