This thesis from the angle of signal detection, first theoretically gives out a RFOG closed signal detection design based on DSP. The signal detection system mainly includes related detection. signal conversion and the formation of feedback saw tooth. Related detection must guarantee signal synchronization sampling, and get the biggest signal noise ratio.

Based on one-cycle control having such merits as anti-perturbation of source, fast dynamic response, robustness, constant frequency, but when converter works in light load its power factor becomes very poor. The modified OCC was proposed, adopting feed-forward compensation control improves influence of power factor at light load, further study adopting independence saw tooth wave completely eliminate influence of power factor at light load.

基于单周期控制有源前端变换器具有抗电源扰动能力强、动态响应快、鲁棒性强、恒频控制等优点，但在轻载时变换器的功率因数变差，提出了改进OCC策略，采用前馈补偿控制改善轻载时对功率因数的影响，进一步研究采用独立的锯齿波电路完全消除轻载时对功率因数的影响，建立改进OCCAFE变换器的数学模型。

一个广阔的，贤能者――覆盖的平原，原产地的野牛和北美大鹿，延伸横跨山谷到到基楚的锯齿状的Teton范围，那突然间上升从山谷底。

Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.

结果表明：钢液对结晶器内的电磁场分布有很大影响；发现了磁感应强度和弯月面高度随电源频率增加而增大的频率范围、磁感应强度和弯月面高度随切缝数目增加呈&锯齿状&增大的规律；研究结果合理地解释了一些实验现象，完善了软接触结晶器电磁连铸技术的理论基础；建议在实际应用中采用分瓣数为16或24分瓣数的结晶器，电源频率应控制在20kHz左右，切缝宽度应控制在1mm左右。
