闭环交流调速系统的S函数辅助设计

Closed-loop AC Speed Regulation System Design Applying S-function

为满足双变量交交变频闭环调速系统的设计,对高速区段的闭环调压调速进行了仿真设计,在此基础上提出了用S函数编写闭环交流调速系统触发模块的仿真方法。使用Simulink的S函数构建闭环交流调速系统的方法能方便地加入各类控制算法,大大提高了仿真灵活性。S函数可以很相似地模拟数字调速系统MCU的程序执行过程,这样仿真结果更接近实际数字控制系统。

Simulation of the closed-loop variable voltage speed regulation in the high-speed section was designed to meet the design of two-variable AC/AC frequency closed-loop AC/AC frequency AC/AC frequency speed regulation system,based on this,the simulation method of programing trigger module with S-function of closed-loop AC speed regulation system was put forward.The method of building closed-loop AC speed regulation system with S-function of simulink can conveniently mix various kinds of control algorithm improving the simulation flexibility greatly.S-function can similarly simulate the implementation process of the program of MCU in digit speed control system,which make the simulation result is more similar to the actual digital control system.
