基于RTX的步进电机寿命实验

步进电机在现代控制中发挥着越来越重要的作用，为了保证产品的可靠性，步进电机的寿命的评估也变得尤为重要。基于Windows的评估系统能够很好的解决这个问题，但是由于Windows操作系统的实时性较差，而步进电机的控制需要精确的时序，所以由其产生的驱动信号时序无法满足要求。采用了Ardence公司的基于Windows的硬实时解决方案RTX ，并结合某项目步进电机寿命实验，总结出了Windows环境下RTX实时应用系统的设计方法与开发流程。实验证明基于RTX产生的驱动信号满足步进电机的运动要求，并且能够不受外部事件的干扰，重复性良好，说明该方法是实时的、稳定的、可靠的。

Life test of stepping motor control base on RTX

Stepping motor is playing an increasingly important role in modern control . In order to guarantee the reliability of the product ,the stepping motor’s life becomes especially important .The evaluation system based on Windows can solve the problem very well . However due to the Windows operating system has poor real‐time performance ,the driving signal timing produced by it can’t meet the requirements of stepping motor which requires precise timing .This paper adopted the hard real‐time solution RTX based on Windows which is produced by Ardence . Combining with the experiments of project about stepping motor life ,the paper summarized the design method and development process of RTX real‐time application system .It is proved by experiments that drive signal generated based on RTX can satisfy the demands of stepping motor .Additionally ,it is not affected by the external events and has good repeatability .As a result ,the method is real‐time ,stable and reliable .
