In order to overcome the difficulty in estimating the ripple component on dc-side capacitor reference voltage, the modified control algorithm is proposed by ignoring the ripple component. Furthermore, the relation between control performance and damping coefficient is researched. In addition, the reasons of voltage source converter inner-loop control overmodulation are also analyzed. Based on the relation between control performance and VSC inner-loop input saturation, damping coefficient is adjusted on-line by fuzzy logic reasoning so that the trade-off between control accuracy and limitation of VSC inner-loop control overmodulation is solved preferably.

由于在线计算直流电容指令电压波动量十分困难，在控制方法的执行中忽略波动量的影响，简化了控制方法的实现；此外，该方法还研究了所注入的阻尼大小对控制效果的影响以及APF内层控制过调制产生的原因，针对无源性控制律跟踪精度的要求与内层控制过调制限幅条件间的矛盾，通过构造模糊逻辑推理环节实现阻尼系数的在线调整，在满足内层控制限幅条件下确保跟踪精度和补偿效果。

Focusing on the problem that the performance of channel estimation is influenced by spatial correlation in multiple input multiple output systems,a parametrical channel estimation method based on estimating multipath parameters is proposed.

Euphotic layer of the sea refers to the layer where phytoplankton can photosynthesize;therefore,the retrieval of the euphotic depth is in favor of estimating ocean primary production.

海水真光层是指海洋浮游植物进行光合作用的水层，海水真光层深度的反演有利于对海洋初级生产力的估算。

It is found that the estimating indexes of heart rate variability of MRR, RMSSD and HRVI etc have different sexual sensitivity. The constant temperature airflow of the simulating natural winds can increase the active level of human's pneumogastric nerves, making human body be flabby, relaxed and comfortable. The result indicates the physiological mechanism of the effect of different winding characteristics on the human thermal comfort.

研究发现MRR、RMSSD和HRVI等心率变异评价指标具有不同的性别敏感性；模拟自然风形式的等温气流吹风作用可提高人体副交感神经的活动水平使人体趋向于松弛、放松、舒适和休息状态，研究结果初步揭示了不同风特性对人体热舒适影响的生理机制。
