In this paper a super-twisting-like structure with adaptive gains is proposed. The structure is parameterized by two scalar gains, both of which adapt, and by an additional time-varying term. The magnitudes of the adaptive terms are allowed to both increase and decrease as appropriate so that they are as small as possible, in the sense that they do not unnecessarily over-bound the uncertainty, ...

Introduction. Recently, wind power generation has grown at an alarming rate in the past decade and will continue to do so as electronic technology continues advance. Purpose. Super-twisting sliding mode control for brushless doubly-fed reluctance generator based on energy conversion system. Methods. This paper deals with robust of a grid-connected driven by variable speed turbine using structur...

The rise of wing-rock motion in delta-wing aircraft has an adverse effect on the manoeuvrability and it may result its crash. This study presents a finite-time control design to tackle dynamic due Wing-Rock aircraft. is developed based methodology Super Twisting Sliding Mode Control (STSMC). Lyapunov stability analysis been pursued ensure asymptotic convergence errors determine finite time. STS...

this paper presents a new observer-based control scheme for a class of nonlinear systems. in the proposed method, nonlinear observer and twisting algorithm controller are employed to realize a sensor-less control strategy for complex systems which makes use of non measurable process information instead of installing as many sensors as possible. due to lack of availability of the complex system ...

In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
