This paper presents the recent control technologies being researched for floating offshore wind energy system (FOWES). FOWES has been getting many attentions recently as an alternative energy system utilizing vast sustainable wind resource away from land with little restriction by human societies, artificial and natural obstacles. However, not only due to the harsh environmental conditions such as strong wind, wave, and current, but also due to the platform motions such as surge, sway, heave, pitch, roll, and yaw, there could occur many problems including less energy capture than expected, frequent emergency stops, turbine structural instability, and fatigues resulting in early failures, which stay the levelized cost of energy (LCOE) still high compared to conventional fixed offshore wind energy system. These risks could be lowered by operating the turbine close to the optimum point and harvesting wind energy efficiently even under strong wind conditions with the properly applied control technologies, while reducing the loads on structural components. Many researches have been actively going on not only by numerical approaches, but also by experimental tests. This study is wrapping the most recent researches on control technologies for promising floating offshore wind energy system according to different substructure designs such as a spar type, semi-submergible type, tension-leg platform (TLP) type, and barge type, and discusses about its challenges as well.

“…However, some papers suggest that wind statistics may be met by using novel improvements in construction of WTs [6,7,10]. In particular, article [7] proposes a novel pitch control method that integrates a non-standard extended Kalman filter-based estimator, where a cascade control structure is developed for the pitch controller receiving the speed reference from a power-speed scheduler. Article [10] introduces a novel dual-rotor WT concept with an auxiliary upwind rotor and a bigger downwind rotor.…”

“…Despite its simplicity, PI controller may not achieve the intended optimum performance due to the nonlinear dynamics of the WTG [7]. To compensate for the unknown time-varying nonlinearities and disturbances various control structures has been used such as nonlinear PI (N-PI) [8], fractional PI [9], cascade control structure [10] and Fault-tolerant control (FTU) to Compensate for the pitch actuator fault [11]. Other strategies to enhance the pitch control include; fuzzy logic control (FLC) [12][13] [14], observer-based bladepitch controller [15] and finite-frequency identification PI controller [16].…”

In this work, a new strategy to control the pitch angle of wind turbine generator is proposed. The strategy is based on designing an intelligent control system capable of maintaining a stable minimum fluctuating power generation. This can be achieved by providing the wind speed information to the controller in advance and hence allowing the controller to take the optimum action in controlling the blade pitch angle. A model based optimizer uses Model Predictive Control (MPC) technique to predict the wind turbine generator future behaviour and select the optimal control actions assisted by the wind speed information while satisfying the power generation constraints. The simulation results show that a significant improvement can be made using the proposed control method.
