计算地震b值程序，基于matlab语言，内附说明书(Calculation of seismic b value procedures, based on MATLAB language, with instructions)

说明：  讨论了直接电流控制的几种控制结构，并建立了相应的仿真模型， 进行了仿真和比较分析。研究了它们在稳态性能和动态性能上的优缺点。其 中重点讨论了采用空间电压矢量调制方法(SVPWM)跟踪给定电压矢量，来控 制STATCOM的电流产生，并且采用直流侧电压可交给定。(Several control structures of direct current control are discussed, and corresponding simulation models are established, and simulation and comparative analysis are carried out. Their advantages and disadvantages in steady state performance and dynamic performance were studied. It focuses on the use of space voltage vector modulation (SVPWM) to track a given voltage vector to control the current generation of the STATCOM, and the DC side voltage can be applied.)
