| 摘 要： | 假定资产价格变化过程服从跳跃-扩散过程，那么基于它的欧式期权就满足一个偏积分-微分方程（PIDE），本文利用差分法来离散这个PIDE方程，用两种迭代方法得到方程的数值解：基于雅可比正则分裂法和预条件共轭梯度法.

| Abstract: | In the excitation controllers of synchronous generator, the phase shifted trigger circuit is used to trigger thyristor and make control angle change along with the variety of voltage distributionacross thyristor in order to adjust excitation,so it is a key technology in automatic excitation controllers. The main function of excitation controllers was introduced, then recited the design of all parts of the DSP phase shifted trigger circuit. Finally, it introduced the pulse failure detection . This design method to be proved has a wide range of phase shife and high sensibility. At the same time the method has simple structure and safe. It can be applied to excitation control of differ synchronization generator. |
