基于NiosⅡ嵌入式处理器的太阳能跟随系统设计

NiosⅡ Embedded Processor-Based Tracking System of Solar Panel

Altera公司的NiosⅡ嵌入式处理器是一种面向用户的、可以灵活定制的通用RISC嵌入式CPU,利用SOPC Buider用户可以很容易的将自己设计的IP集成其中。基于此,在太阳能跟随系统设计中,可以将设计的PWM输出和AD采样模块、编码器单元自定义外设模块集成到SOPC Buider上,并且可以在系统上利用软件实现电压空间矢量算法控制智能模块,从而可以很好的控制交流永磁同步电机带动太阳板跟随太阳转动。

The Altera company＇s NiosⅡ embedded processor is one of the user-oriented and can be flexibly customized RISC CPU.The user can integrate his own IP to the system with the help of SOPC Buider.This paper customizes the PWM IP,AD sampling IP and the encoder unit IP.Moreover.It can also be used the software to achieve the SVPWM Algorithm which can control the Intelligent module.Consideing this,the PMSM can easily drive the rotating solar panel to follow the sun.
