结构稳定性

In order to improve the accuracy of the output voltage of a LDO,which consumes low quiescent current,a novel dual active compensation technique is used to design a LDO.It can produce two system zeros varying from load current to cancel the negative effect of the pole at different loads on the system's stability.

According to the analysis and computational results in this thesis, although the actual structure and work conditions of the pressure vessel in nuclear power station are much more complex than that of the pressure vessel model, the program FEARPV still can get quite good convergence on the plasticity andcontact iteration. And also the program FEARPV has good value stability, and good regularity. During the heating, compression, constant temperature, constant pressure, cooling and decompression process, the regularity is basically in common with that of the pressure vessel model.
