The hydrostatic wind turbine (HWT) is a type of wind turbine that uses hydrostatic transmission (HST) drivetrain to replace the traditional gearbox drivetrain. Without the fragile and expensive gearbox and power converters, HWT can potentially reduce the maintenance costs owing to the gearbox and power converter failures in wind power system, especially in offshore cases. We design an MFAC torque controller to regulate the pump torque of the HWT and compared with an torque controller. Then we design an MFAC pitch controller to stabilise the rotor speed of HWT and compared with a gain‐scheduling proportional‐integral (PI) controller and a gain‐scheduling PI controller with antiwindup (PIAW). The results indicate that MFAC torque controller provides more effective tracking performance than the controller and that MFAC pitch controller shows better rotor speed stabilisation performance in comparison with the gain‐scheduling PI controller and PIAW.

通过无模型自适应控制方案实现静水力风力发电机的发电控制

静液压风力涡轮机（HWT）是一种使用静液压传动（HST）传动系统替代传统齿轮箱传动系统的风力涡轮机。如果没有脆弱且昂贵的变速箱和功率转换器，由于风力发电系统中变速箱和功率转换器的故障，尤其是在海上情况下，HWT可以潜在地降低维护成本。我们设计了MFAC扭矩控制器来调节HWT的泵扭矩，并与扭矩控制器进行了比较。然后，我们设计了一个MFAC变桨控制器，以稳定HWT的转子速度，并与增益调度比例积分（PI）控制器和带反饱和（PIAW）的增益调度PI控制器进行比较。结果表明，MFAC转矩控制器提供了比跟踪控制器更有效的跟踪性能。 与增益调度PI控制器和PIAW相比，MFAC变桨控制器显示出更好的转子速度稳定性能。
