Improved control of individual blade pitch for wind turbines

Sensors and Actuators A: Physical, 2013
This paper is concerned with improved control of individual blade pitch for wind turbines. The controller is based on the proportional-integral-plus (PIP) algorithm, considered an extension of conventional proportional-integral/proportional-integral-derivative (PI/PID) controllers, in which full state variable feedback control is implemented directly ...

The Realization of Individual Pitch Control

Applied Mechanics and Materials, 2013
This paper describes the classical individual pitch control algorithm. Firstly, transform the out-of-plane bending moment of each blade in the rotational coordinate to the hub loads proportional to the tilt and yaw moment in the fixed coordinate. Secondly, design the PI controllers to minimize the load.

Individual pitch control using LIDAR measurements

2012 IEEE International Conference on Control Applications, 2012
In this work the problem of individual pitch control of a variable-speed variable-pitch wind turbine in the full load region is considered. Model predictive control (MPC) is used to solve the problem. However as the plant is nonlinear and time varying, a new approach is proposed to simplify the optimization problem.

Individual variable pitch control of wind turbines

2011 International Conference on Electrical Machines and Systems, 2011
Focusing on the tilt moment and yaw moment caused by asymmetric wind, aerodynamic model for individual pitch control of large-scale wind turbine was established. As the aerodynamic model have characteristics of multiple variables, strong coupling and time-varying.

Impact of individual pitch control on pitch actuators in megawatt wind turbines

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
Individual pitch control is seen as a promising control technique for load reduction of the rotor blades in megawatt wind turbines. As the rotor blades are getting bigger and bigger, the asymmetric loads due to wind speed variations across the rotor area are increasing, too.
