从瞬时有功功率的角度出发，给出了新的双馈电机力矩的控制方法。在控制中只需检测交流侧电流电压，不需要位置传感器。
写得好烂。看不懂，先放着

基于直接转矩控制（DTC），还需要进一步了解，不过现在这种方法似乎用的不多？
在模型参考自适应方法的基础上，将一种“改进的无传感器技术”引入DIFG
仍然是需要检测转子电压，转子电流和定子电流，得到定子磁链，再用模型自适应的方法得到转速，转速积分得到转子位置。

针对常规的基于转子电流的双馈风力发电机模型参考自适应转子位置观测器的不足,提出了一种基于转子电流的模型参考自适应、模糊控制双馈风力发电机位置观测器的设计方法。该方法将参数自整定模糊P I控制技术引入转子位置观测器的设计中,以提高转子观测器的跟踪效果和动态品质。

双馈风电；虚拟同步机控制；电压故障；次同步稳定性；特高压直流输电
主要就是虚拟同步机控制以增加DFIG的惯性，很新的控制方式（是否意味着矢量控制、功率控制就outdated了？）

在转速控制阶段，采用定子磁场定向的矢量控制，通过采集电网电压、定子电压、转子电流实现定子磁链位置估计，根据定子磁链的位置进行转子位置估计
忽略了变压器电势的影响，所以在位置估计中会因d-q轴上定子电流的变化而增大位置估计误差，尤其在电流急剧变化时影响更加显著．

针对定子电压的非正弦性，定子侧变流器和转子侧变流器通过间接气隙磁链定向控制。为降低无位置传感器运行的参数依赖性，采用基于气隙磁链的模型参考自适应控制策略。
利用小信号模型分析了系统的稳定性；又分析了电机参数对这种控制策略的影响（有影响，但可以接受）

基于定子磁场定向控制
通过定子电流计算出同步坐标系中的转子电流，得到转子在定子磁链坐标系下的位置；而定子磁链位置通过检测电网电压得到

通过测量定子电压计算定子静止坐标下的定子磁链矢量，同时通过测量的转子电流和重构得到的转子电压计算转子坐标系的定子磁链矢量，根据定子磁链矢量在不同坐标系下的位置获得转子位置角度.
和已有方法相比，该方法仅需测量定子电压和转子电流作为反馈量，计算量较小且不需要定子电流信息。
这是基于定子磁链定向控制的方法

This paper presents an invention, the rotor position phase lock loop (PLL), which enables maximum power point
(MPPT) tracking of wind by doubly-fed induction generators without needing a tachometer, an absolute position encoder, or an anemometer. The rotor position PLL is parameter variation
insensitive, requiring only an estimate of the magnetization inductance for it to operate. It is also insensitive to noise in the electrical measurements.

简单来说，就是利用电感显著性（电感会随着转子的角度变化而改变）去测算转子的位置。具体操作是向转子侧注入高频旋转电压信号，然后通过滤波、PLL锁相环获得转子电流相位和定子中感应出的高频电压相位，作差得到转子位置

Implementation of decoupled P -Q control of doubly fed induction generators requires the positions of the rotors to be known. The rotor position phase-lock loop (PLL) is an invention that extracts rotor position and speed simultaneously by “sensorless” means. The rotor position PLL is parameter insensitive because, apart from an approximate value of the magnetization reactance, knowledge of the other parameters is not
required for it to function. Experimental results obtained under
noisy conditions demonstrate that it is also insensitive to noise.
和另外一篇基本完全一样啊；转到两相静止坐标系，这里的PLL甚至更加复杂；（没有细看）

The proposed slip speed/position estimator is based on the association of the phase locked loop and the sliding
mode observer.
The proposed sliding mode observer uses the three phase stator currents and the back electromotive force as state variables.

This paper presents an analysis of a model reference adaptive system (MRAS) observer for the sensorless control of a standalone doubly fed induction generator (DFIG). The analysis allows the formal design of the MRAS observer of given dynamics
and further allows the prediction of rotor position estimation errors under parameter mismatch. 好像没有什么特别的，就是一个基于定子磁链MRAS，有改进的性能。
之前吴超的MARS方法和这个基本完全一致啊（）

没有用矢量控制，而是使用了direct power control
用BESS取代了网侧逆变器，这在海上风电的场景下大抵是不可行的吧；但是也可以去看看他的算法？？？感觉是比较基础的那种

The method proposed is based on the phase comparison of an estimated air-gap power vector and the measured rotor currents in a common reference frame. The proposed method can
be implemented in the rotor or in the field reference frames with a hysteresis or proportional–integral controller

Most control methods for grid-connected DFIG require knowledge of the slip angle. To avoid the disadvantages of mechanical encoders, this paper proposes a new slip angle estimator with the target of minimizing the required number of DFIG parameters（减少对电机参数的依赖） and avoiding stator flux estimation. (回避估算定子磁链）The proposed estimator does not ignore the stator leakage inductance, which slightly improves the model accuracy compared with the rotor position PLL.

a research work on reduced current sensor based position-sensorless control is appears to be missing in existing literature for grid-connected DFIG systems.
Position-sensorless field-oriented control of doubly fed induction generator (DFIG) necessitates at least 4–6 current sensors. In this paper, a novel rotor position and current estimation algorithms are proposed, which make the control of DFIG feasible using only three current sensors.（增强硬件的可靠性，减小系统复杂度）
只用了一个逆变器，用BESS取代了另外一个（有点意思）

For this purpose（最大能量捕获以及高质量电能输出）, we propose a dynamic state estimation (DSE，动态状态估计不会啊)-based sliding mode control (SMC，滑模控制) strategy to achieve such control purposes for doubly fed induction generator (DFIG) wind turbines connected to multi-machine power grids. To resolve this issue, a novel dechattering method is designed so as to minimize the unnecessary switchings
在高风速的条件下（本文主要卖点）这种控制策略有良好的表现

The method is based on the phase comparison of the actual and the estimated rotor currents using the classical model of the machine；
It has some similarity to the model reference adaptive system methodology, but uses a hysteresis comparator instead of a proportional integral (PI) controller. In this way, the method does not need parameter determination for the controllers and shows a considerable independence of parameter uncertainties
