Multi‐Domain Linear Hybrid Semi‐Mechanism Modeling and Two‐Level Coordinated Control for a Cascade Dual‐Rotor Wind Turbine

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT For a newly emerging kind of cascade dual‐rotor wind turbine (CDR‐WT), the coordinated control of its front and rear rotor faces significant challenges. To solve this problem, a novel modeling and control design approach is presented in this paper.

Complementary Control Strategies for Floating Offshore Wind Turbines: Gain Scheduling With LQG Enhancement and Equivalent Wind Speed–Based Individual Pitch

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT This study investigates control strategies for large‐scale floating offshore wind turbines using the semi‐submersible IEA 15‐MW turbine as a benchmark. A gain‐scheduled PI (GSPI) controller is firstly established as the baseline for collective pitch control (CPC).

Analysis of a Sampling Servo Mechanism

Journal of Applied Physics, 1950
An analysis of a sampling servo mechanism with an error-clamping device and linear forward and return paths is given. The method leads to a determination of the continuous output of the system in terms of quadratures and gives explicitly the value of the output at the discrete sampling instants.

Adaptive friction compensation of servo mechanisms

International Journal of Systems Science, 2001
In this paper, adaptive friction compensation is investigated using both model-based and neural network (non-model-based) parametrization techniques. After a comprehensive list of commonly used models for friction is presented, model-based and non-modelbased adaptive friction controllers are developed with guaranteed closed-loop stability.
