摘要
交流永磁同步电机可以采用磁场定向控制或直接转矩控制方法,分析了磁场定向控制方法和硬件结构,实现其数字控制。使用德州仪器公司的TMS320F2812数字信号处理器作为主控芯片,在CCS集成开发平台上设计了以磁场定向为控制方法的三闭环伺服控制系统。首先介绍了系统的总体硬件设计和主要电路设计,对电路设计中关键问题进行分析。接着介绍了系统整体软件框架和各模块的具体软件设计,并设计了带有积分校正的PI控制器实现系统的三环控制,得到了较好的控制效果。
AC PMSM can adopt field oriented or direct torque control method.The field-oriented control method and hardware architecture is analyzed to achieve its digital control.Using the Texas Instru-ments TMS320F2812 digital signal processor as the master chip,the three closed-loop servo control system is designed in the CCS integrated development platform.First the overall hardware design and the major cir-cuit design is introduced and the key problems in circuit design are analyzed.And then the overall software frame and specific design for every module is presented as well as a PI controller with integral correction is designed to realize three closed-loop control of system,thus preferable control effect is obtained.
