摘要
自由活塞式斯特林直线电机发电系统因具有高效、长时间在轨、应用能源广泛等性能而得到广泛关注。位置检测方式在自由活塞式斯特林直线电机发电系统中占有重要的地位,可以从中分析发动机设计的合理性与系统工作的稳定性。为了获得自由活塞式斯特林直线电机发电系统由自启动的电动状态到发电状态的动态过程,并为了减小系统的体积、提高系统的密封性,设计了一种基于无位置检测的压力波测试方法。该方法采用一种新型的压力波传感器,配合适当的供电、调理、采集电路,可以实时检测到发动机动子的位置,进而实现发电系统的控制。
Free piston stirling engine linear motor power generation system earns widespread attracts for the possession of properties as high‐efficiency , long term on track and broad application resource . Position detection plays an important part on the Free Piston Stirling Engine Linear Motor Power Generation System ,from which the rationality and stability of the motor design working system can be analyzed .To acquire the dynamic procedure from the starting power‐driven status to the power generating status of Free Piston Stirling Engine Linear Motor Power Generation System ,and to decrease the system volume and improve the leakproofness ,a pressure wave testing method based on sensorless position detection was designed .This method makes use of a new pressure wave sensor ,accompanied with appropriate power‐supply ,conditioning and acquisition circuit ,it detects the position of the engine’s active cell in real time ,thus to realize the control of the power generating system .
