摘要:
风速的强随机性与风力发电机建模的不确定性给风力发电系统的干扰抑制带来了极大的挑战. 设计了一种新型非线性采样控制器,以实现风力发电系统的输出功率能抑制干扰信号. 首先,将系统中的非线性及干扰等效为有界项,建立系统的近似数学模型,随后设计连续状态反馈控制器以估计压制增益L,并构造能满足稳定性要求及干扰抑制的采样控制器,便于在计算机中实现. 最后,基于余弦干扰输入算例验证了采样控制器的稳定性及干扰抑制特性.
Abstract:
The strong randomness of wind speed and the uncertainty of wind turbine modeling bring about great challenges to the disturbance attenuation of wind turbine system. In this paper,a new type of non-linear sample-data controller is designed to realize the output power to suppress the disturbance signal. Firstly,the non-linearity and disturbance in the system are equivalent to bounded terms,and the approximate mathematical model of the system is established. Secondly,a continuous state feedback controller is designed to estimate the suppression gain. Thirdly,a sampling controller is constructed to meet the stability requirements and disturbance suppression,which is easy to implement in computer. Finally,the stability and disturbance suppression characteristics of the sampled-data controller are verified by a cosine disturbance input example.
