Abstract

A bearingless permanent magnet synchronous motor (BPMSM) control system has a large number of control variables but has a small amount of data variables. So, adopting optimal coding scheme is demanded in its human-computer interaction. Based on the analysis of data format in serial port communication and data types of control variables, an optimal scheme of data split and combination and a coding one are given. A software synchronization strategy is proposed to keep data integrity. A decoding vectors table of linear pointer array structure and a sending descriptors table of single list structure are introduced to accelerate decoding process and implement dynamic adjustment of sending contents respectively. With this human-computer interaction strategy, code extension is easily realized and has no influence on the efficiency of program. The results show that the BPMSM operates stably, and smooth communication, integrated data, easy operation, convenient code extension and simple maintenance are obtained with this human-computer interaction strategy.

基于最优通信协议的BPMSM控制系统人机交互设计

无轴承永磁同步电机(BPMSM)控制系统具有大量的控制变量，而数据变量却很少。因此，在人机交互中需要采用最优的编码方案。在分析串口通信数据格式和控制变量数据类型的基础上，给出了数据分割组合的优化方案和编码方案。为了保证数据的完整性，提出了一种软件同步策略。引入线性指针数组结构的解码向量表和单表结构的发送描述符表，分别加快解码速度和实现发送内容的动态调整。采用这种人机交互策略，易于实现代码扩展，且不影响程序的运行效率。结果表明，采用该人机交互策略，BPMSM运行稳定，具有通信顺畅、数据集成、操作简单、代码扩展方便、维护简单等优点。
