“…Nonetheless, we employ a polynomial approximation of the latter for the purpose of the synthesis of the controller. Referring to a two-mass model as in [10], and as shown in Fig. 1, then, the low speed shaft torque T ls acts as a braking torque on the rotor, the generator is driven by the high speed torque T hs , and braked by the generator electromagnetic torque T g .…”

“…In the sequel we only consider WTs that have to be strictly deloaded with respect to their P o i . Following [10], the local control is composed of a first loop to control ω r . We impose a first order dynamics to the rotor speed tracking error ε ω ω re f − ω r :ε ω + a 0 ε ω = 0, by choosing a 0 ∈ R + .…”

“…The overall approach can be seen as a novel wind farm level maximum power point tracking (MPPT) technique. [10] proposes a FL controller for variable-speed fixed-pitch WTs to track a desired power reference, but it is only applicable at high wind speed. [11] capitalizes on a combined FL, and model predictive control technique enabling general power tracking in the whole WT operating envelope, but it does not particularly simplify the design of a distributed control law.…”

“…[11] capitalizes on a combined FL, and model predictive control technique enabling general power tracking in the whole WT operating envelope, but it does not particularly simplify the design of a distributed control law. Thus, based on [10] we make use of a new FL application to WTs to let power tracking below the rated wind speed. Secondly, under the assumption of discrete-time communication among the WTs, we employ a distributed PID-like control architecture to force the system to stabilize around the optimal power sharing set points under system disturbances.…”

Abstract-In this paper we address the problem of power sharing among the wind turbines (WTs) belonging to a wind farm. The objective is to maximize the power extraction under the wake effect, and in the presence of wind disturbances. Because of the latter, WTs may fail in respecting the optimal power sharing gains. These are restored by employing a consensus control among the WTs. In particular, under the assumption of discrete-time communication among the WTs, we propose a distributed PID-like consensus approach that enhances the rejection of the wind disturbances by providing the power references to the local WT controllers. The latter are designed by employing a novel feedback linearization control that, acting simultaneously on the WT rotor speed and the pitch angle, guarantees the tracking of general deloaded power references. The obtained results are validated on a 6-WT wind farm example.

“…In Muldaji et al (1998), authors have evaluated a variable-speed, stall-regulated strategy that eliminates the need for ancillary aerodynamic control systems. In Boukhezzar and Siguerdidjane (2005), a cascade structure, non-linear controller was proposed; however, parametric uncertainties of the system were not taken into account. In Song, Dhinarakaran, and Bao (2000), authors presented two non-linear controllers:…”

In this study, a robust backstepping approach for the control problem of the variable-speed wind turbine with a permanent magnet synchronous generator is presented. Specifically, to overcome the negative effects of parametric uncertainties in both mechanical and electrical subsystems, a robust controller with a differentiable compensation term is proposed. The proposed methodology ensures the generator velocity tracking error to uniformly approach a small bound where practical tracking is achieved. Stability of the overall system is ensured by Lyapunov-based arguments. Comparative simulation studies with a standard proportional-integral-type controller are performed to illustrate the effectiveness, feasibility and efficiency of the proposed controller.

This paper presents an educational software tool, called wtControlGUI, whose main purpose is to show the applicability and performance of different decoupling control strategies in wind turbines. Nowadays, wind turbines are a very important field in control engineering. Therefore, from an educational point of view, the tool also aims to improve the learning of multivariable control concepts applied on this field. In addition, wtControlGUI allows for testing and controlling of a lab-scale system which emulates the dynamic response of a large-scale wind turbine. The designed graphical user interface essentially allows simulation and experimental testing of decoupling networks and other multivariable methodologies, such as robust or decentralized control strategies. The tool is available for master degree students in control engineering. A survey was performed to evaluate the effectiveness of the proposed tool when it is used in educational related tasks. ß 2016 Wiley Periodicals, Inc.
