说明： 超紧耦合是 GPS/INS 组合导航系统的最新研究方向，它采用 INS 测得的载体动态信息辅助 GPS 接收机跟踪环
路，消除卫星信号中由于载体与卫星之间相对运动所产生的频率偏移，提高接收机在高动态环境下载波跟踪性能，同时还
可以压缩带宽，有效增强接收机抗干扰性能。介绍 GPS/INS 超紧耦合技术，给出 INS 辅助 GPS 载波跟踪环路结构图和相应
的数学模型，分析 INS 辅助 GPS 跟踪环路在动态环境下的动态残留及其对环路相位误差的影响，并进行了模型仿真，最后
对仿真结果进行了验证分析。仿真结果显示，辅助动态残留及其导致的环路相位误差的大小与加加速度、环路辅助时间间
隔成正比。
(The ultra-tightly coupled GPS/INS integrated navigation system latest research direction, it adopted the INS measured the carrier dynamic information auxiliary GPS receiver tracking loop to eliminate the satellite signal frequency due to the relative motion between the carrier and the satellite offset improve the receiver in high dynamic environment download wave tracking performance, but also can compress bandwidth, effectively enhance the anti-jamming performance of the receiver. Introduced GPS/INS ultra-tight coupling technology gives INS assisted GPS carrier tracking loop diagram and the corresponding mathematical model to analyze the impact of the INS assisted GPS tracking loop dynamic residues in a dynamic environment and the loop phase error, and model simulation, and analysis of simulation results verified. Simulation results show that the the residual secondary dynamic its resulting size of the error loop phase and jerk loop secondary is proportional to the time interval.)

OLED DISPLAY MODULE
I m using a 160x128 Graphic OLED Display from Densitron (DD-160128FC-2A) with the ATmega1281. The LCD is controlled via a SEPS525 OLED Driver IC. I use the LCD in 8bit parallel mode.
Both the LCD and controller datasheet is VERY vague and I struggle to get the LCD to respond.
The OLED controller is configured via 3 registers, IR (Index), WDR (Write Data Register) & RDR (Read Data Register).
It is the first time I come across this register INDEXING method and can t find any examples or discussions on the control sequence.

Study-of-VSC-HVDC-Controller-
风电潮流的波动会引起并网系统公共连接点（PCC）电压的波动。在基于电压源换流
器的高压直流输电（VSC-HVDC）交直流混合风电场并网系统中，控制VSC-HVDC 送端站注入
到PCC 点的无功功率可以抑制电压波动。本文讨论了VSC-HVDC 的无功功率控制器和定电压控制
器抑制电压波动的原理。基于电磁暂态软件PSCAD/EMTDC 建立了并网风电场模型、VSC-HVDC
模型及控制系统模型。仿真结果表明VSC-HVDC 采用定电压控制器的并网系统能更好的抑制电
压波动，采用无功功率控制器的系统具有较好的风电场并网性能。(Reactive power variation of integration wind farm may cause point of common
coupling （PCC） voltage fluctuation. In hybrid wind farm integration system based on HVDC of
voltage source converter （VSC-HVDC）, the voltage fluctuation can be alleviated by compensating
reactive power to PCC from VSC-HVDC sending end. Therefore, the reactive power controller and the
stable voltage controller to alleviate voltage fluctuation are studied in the paper. The integration wind
farm, VSC-HVDC and their controller models are set up by PSCAD/EMTDC. The simulation results
show that the integration system adopted stable voltage controller has a better performance to alleviate
voltage fluctuation. However the system adopted reactive controller has a good wind farm integration
capability.)
