The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided.

In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.

For the current drive (use -v to list drive types). An invalid drive will

首先用 drivex -v 来看看驱动器类型和对应的说明，我的所有驱动器如下所示

In summary, the drive current by Alfvén waves can be enhanced by plasma rotation The negative magnetic shear is favorable for the efficiency of the current drive by Alfvén waves Moreover, in the reversed shear configuration the current drive due to Alfvén waves in an rotation plasma can obviously change the plasma current profile The Alfvén wave current drive may be useful in controlling the current profile in order to suppress magnetohydrodynamic instabilities.

另外，我们还发现负剪切区域愈大，同时安全因子极小值q〓愈小，对阿尔芬波电流驱动愈好。总之，等离子体极向旋转能够增强阿尔芬波电流驱动，负磁剪切对阿尔芬波电流驱动是有利的。另外，反磁剪切位形下旋转等离子体的阿尔芬波电流驱动可以明显改善等离子体电流剖面。

We found that in the case of neglecting magnetic shear, the plasma current also can be driven by the shear Alfvén wave and the circularly polarized wave, respectively, the efficiency of current drive in the rotation plasma is independent of the plasma density In addition, it is found that whether m=0 or m≠ 0, the effect of the magnetic shear on the compressional Alfvén wave current drive makes the efficiency be dependent on the plasma density and inversely proportional to it.

当考虑旋转效应而不考虑磁剪切效应时，等离子体平板模型下平面极化压缩阿尔芬波能够驱动旋转等离子体电流，驱动效率也与等离子体密度无关，却与旋转大小成正比，这与Avinash[Phys Plasmas 4，2204（1997）]的结论一致。我们发现在这种情况下剪切阿尔芬波和圆偏振阿尔芬波都可以驱动旋转等离子体电流，旋转效应引起的电流驱动与密度无关。
