摘要
现有旋转式斯特林制冷机控制器使用的是基于 PID控制的无刷直流电机, 存在控温波动较大、可靠性较低等问题。基于磁场定向控制的永磁同步电机控制性能卓越、运行平稳、损耗低, 将其作为提高斯特林制冷机性能的有效途径。根据这一方案进行硬件及软件设计, 并给出实际电路测试结果。实验表明基于 FOC及 PMSM的斯特林制冷机控制系统可以作为提高斯特林制冷机性能的措施和途径。
Abstract
Today’s rotary Stirling cryocooler controller is based on the PID control of brushless DC motor, which has issues such as control temperature fluctuation, lower reliability and so on. Permanent Magnet Synchronous Motor under Field Oriented Control has excellent control performance, smooth operation and low energy consumption. It is an effective way to improve Stirling cryocooler performance. Hardware and software are designed for this program. And practical circuit test results are given. Experiments show control systems based on FOC and PMSM can improve Stirling cryocooler performance.
