“…In order to compare the EMPC with the baseline control, the average power P and DEL in the curve are normalized by Equation (7), so as to achieve a more intuitive comparison effect, where norm  represents the normalized value, EMPC  represents the average power generation P and DEL in EMPC, BC  represents the same parameters under the BC. The BC yaw controller in Bladed uses the average wind direction in the last discrete period as the nacelle position reference of the current control period [22].…”

“…These studies showed that yaw control is potentially helpful for increasing the power generation and reducing the fatigue load on key parts of the wind turbine. [7] compared proportional integral derivative (PID) control, fuzzy control and MPC control, and then pointed out that logic control still dominates yaw control. In the research of wind turbine yaw controller, more power capture and less use of yaw actuator have always been contradictory issues.…”

With the increasing capacity of wind turbines, the importance of the yaw system has gradually become more prominent. The supervisory control and data acquisition (SCADA) system of XEMC Windpower Co., Ltd. is used in this paper to analyze the yaw data of the No. 5 wind turbine of Baozhong Mountain Wind Farm in Hunan Province. In order to evaluate the power generation and the damage equivalent load (DEL) of the yaw bearing during the yaw process, an economic model predictive control (EMPC) yaw strategy based on light detection and ranging (LIDAR) was proposed. EMPC takes the yaw error and wind speed as the disturbance of the cost function (CF) at the same time by establishing the yaw bearing DEL look-up table in advance. Discrete adaptive yaw speed control set is proposed to adapt to different wind conditionssets. Finally, the effectiveness of EMPC is verified using the model of XE112-2000 wind turbine in simulation software Bladed.

“…In recent years, the main control methods involved in the yaw system of HAWT include neural network control [5,6], variable structure adaptive fuzzy logic control [7], model predictive control (MPC) [8,9], proportional integral differential (PID) control [10] and so on [11][12][13][14]. Most of the existing literatures focus on the traditional gear-driven yaw system, and only a few of them are based on MYS [2][3][4][5][6][7][8].…”

The maglev yaw system (MYS) of wind turbine adopts the maglev-driving technique instead of the traditional gear-driving technique, so it has the advantages of short downtime and low cost of operation and maintenance. However, it is vulnerable to the nonlinear time-varying disturbance caused by the random change of wind speed and direction. This paper proposes a dual-loop suspension control strategy based on the finite control set model predictive control (FCS-MPC) with state feedback control (SFC) to improve the dynamic response and anti-disturbance ability of the MYS. First, the mathematical models of the MYS are built. Second, in order to realise the stable suspension control, the outer loop controller for suspension air gap tracking is designed by combining SFC with proportional integral differential, and the inner loop controller for maglev current tracking is designed by adopting FCS-MPC with delay compensation. Finally, the simulation and experimental results show that the proposed control strategy has better robustness and dynamic response property comparing with the existing control strategies, and the maglev system of MYS can realise smooth and reliable operation. The proposed suspension control strategy is substantiated to be effective and feasible.

In this work a control strategy based on the mathematical model of an active yaw system for a 20 KW horizontal axis wind turbine is proposed. It allows to increase its efficiency in the presence of changes in the intensity and direction of the wind. The inverse optimal control strategy is implemented based on the mathematical model using the equations of state that represent the dynamics of the yaw system, whose model was obtained with the FAST program, specialized software for modeling wind turbines, which allows obtaining the mathematical model of the orientation system in a more precise way. The results are presented via simulation, where the control strategy is validated in the presence of disturbances. The contribution of this work lies in the application of the optimal control strategy and the tuning parameter search strategy of the control law.
