摘要

本文提出了风力发电机组在风扰动影响下的输出转矩和功率调节的最优控制方案。所考虑的系统是一个动态力学模型,具有螺距和发电机转矩执行器,用于控制螺距和发电机转矩。线性二次型调节器(LQR)线性矩阵不等式(LMI)形式的性能比较了积分作用线性二次型调节器(LQRI)和模型预测控制(MPC)对风扰动阶跃变化的响应。Matlab仿真结果表明,LQRI的性能优于LQR控制器和MPC控制器。

Optimal Control of Wind Turbines under Islanded Operation
In this paper, an optimal control scheme for wind turbine output torque and power regulation under the influence of wind disturbances is presented. The system considered is a dynamic mechanical-based model with pitch and generator torque actuators for controlling the pitch and generator torque. The performance of linear matrix inequality (LMI) formalism of linear quadratic regulator (LQR); linear quadratic regulator with integral action (LQRI) and model predictive control (MPC) were compared in response to a step change in wind disturbance. It is shown by Matlab simulation that the LQRI outperformed both LQR and MPC controllers.
