Model-based wind turbine control design with power tracking capability: A wind-tunnel validation

Evaluation of different power tracking operating strategies considering turbine loading and power dynamics

“…While we have designed a basic controller that only operates based on the rotational speed and pitch angle measurement as shown in Pöschke et al (2022), the resulting load profiles may be influenced by the introduction of additional performance shaping control architectures. To achieve this, additional degrees of freedom may be introduced into the modeling and control design process, yielding feedback loops actively shaping the closed-loop dynamics of compo-nents like the drivetrain or the tower movement, as discussed in, e.g., Bossanyi (2003) or specifically for the applied disturbance observer-based approach used here in Pöschke et al (2020).…”

“…A lot of classical problems from control theory can be recast into linear matrix inequality design constraints (Boyd et al, 1994;VanAntwerp and Braatz, 2000), where the Takagi-Sugeno framework represents one possible way of obtaining the necessarily involved system description. Details about the applied control scheme and its design process for wind turbines are discussed in Pöschke et al (2020Pöschke et al ( , 2022. Whereas in Pöschke et al ( 2020) several degrees of freedom including tower or drivetrain dynamics are considered and actively damped, the applied controller in this work uses the rotational dynamics as the only degree of freedom and measured quantity similarly to the experimental wind tunnel validation discussed in Pöschke et al (2022).…”

“…The model-based design process can be applied to widespread linearization points determined by the control engineer's choice of operational strategy. Whereas in Pöschke et al (2020Pöschke et al ( , 2022 OS1 is applied for the studies involving power tracking and load analysis, within this work OS2 is added. Effectively, this is achieved by introducing an additional variable as the premise in the Takagi-Sugeno framework used for the nonlinear modeling of the turbine dynamics; i.e., z 2 = n OS .…”

Wind energy conversion technologies and engineering approaches to enhancing wind power generation: A review

“…Basically, the model-based design (MBD) approach was introduced against that of physical prototyping to smooth the design development and optimization processes in the particular case of complex systems including WECSs. In a number of recent studies [ 62 , 63 , 64 , 65 ], MBD was reported to be methodologically effective and efficient particularly for modeling and evaluating WECSs control system designs based on the proposed control design strategies. In the typical case, a WECS control system model can be simulated, tested, and preliminarily validated based on a model predictive algorithm and by using MATLAB/SIMULINK software platform, external target computer, and controller.…”
