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

简单工资登记系统 一 ：程序设计目的：做此程序目的在于熟悉数据库开发的过程及其与界面连接的方法，故简化了数据库中表和物理存储的设计过程。不同公司的工资管理不一样，功能也可以非常复杂，而开发流程大致相同，现在熟悉方法对今后针对具体公司的具体系统做开发更有意义。-simple wage a registration system : procedures designed to : do purpose of this procedure is familiar with the process of database development and its link with the interface, it simplifies the database table and the physical storage of the design process. Different companies in the wages not the same, functions can be extremely complex, and the development process similar to that now familiar with the method in the future, targeted at specific companies do a specific system development more meaningful.
