感应电机的运行
INDUCTION MOTOR RUN
(Currents and speed as state variables)
The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45.
The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS.
The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN

很多的程序都要用到数据库结合的操作，这里举例ACCESS，因为ACCESS在中小型VC系统开发中是最常用到的，如果程序的移植，如果对于很初级的用户来说，你还需要他到配置面板中进行数据源配置的话，那就有点说不过去了。-many of the procedures that make use of databases, the operation here for ACCESS, ACCESS SMEs in VC system development is the most commonly used, and if the transplant procedure, if for the very primary users, you also need him to the configuration panel for the configuration data sources, then it would have point justified.
