The aim of this paper is to propose a new design variable speed wind turbine control by discrete‐time sliding mode approach. The control objective is to obtain a maximum extraction of wind energy, while reducing mechanical loads and rotor speed tracking combined with an electromagnetic torque. For this application, we designed a discrete time sliding mode control using the equivalent discrete time...
The aim of this paper is to propose a new design variable speed wind turbine control by discrete-time sliding mode approach. This methodology is designed for linear saturated system. The saturation constraint is reported on inputs vector. To this end, the back stepping design procedure is followed to construct a suitable sliding manifold that guarantees the attainment of a stabilization control objective...
This paper proposes a new design approach of discrete sliding mode control for variable speed wind turbine in presence of saturation constraint. The saturation is reported on inputs vector. The design of the sliding surface is formulated as a pole assignment of linear saturated systems in a specific region through convex optimization. It is well know that the mechanisms are investigated in term of...
This paper deals with the robust control of variable speed, pitch regulated for a modeling two-mass gear train wind turbine. It is well know that the mechanisms are investigated in term of the most proposed assumptions to deal with the damping, shaft stiffness and inertia effect of the gear. The existing control techniques do not take into account the dynamical aspect of the wind and the turbine,...
This paper deals with robust control of saturated systems. It presents a design methodology of sliding mode control of a class of linear systems with the presence of both constraint of saturation and norm bounded uncertainty. The design of the sliding surface is formulated as a problem of root clustering of reduced uncertain system, what leads to the development of a continuous and non-linear control...
The balancing of an inverted pendulum with an horizontal motion of the cart is a classical problem treated in the area of control. In this paper we present briefly the inverted pendulum and its modeling. After that we describe two controllers to swing a pendulum attached to a cart from an initial downwards position to an upright position and maintain that state. The first is the sliding mode control...
