| 摘 要： | 通过研究卫星反作用飞轮的总线化伺服驱动及其系统重构问题,构建了可靠的无刷直流电动机功率驱动主回路,研制了可以采样三相绕组电流的磁感应式传感器及泵生电压自动抑制电路。对普通的M/T测速算法进行了改进,并仅以两组相互备份的六个位置传感器完成了数字转速测量和换相控制。规划了现场总线协议,设计了总线式的全数字化飞轮力矩/速度双模式伺服驱动器的知识产权内核及系统级专用芯片,构造了冗余型可重构控制器,提出了多种重构方案以及相应的实现算法。在现场可编程门阵列工艺中最终实现了飞轮的片上伺服系统;测试结果表明,该系统在整个四象限区域内均具有良好的动态和静态运行性能。

| Abstract: | A design scheme of bus-based servo drive controller and system reconfiguration for the satellite retroaction flywheel was investigated.In this scheme,a reliable power inverter as well as a pumped voltage suppresser was constructed,and a magnetic induction sensor was developed to monitor the three-phase motor currents.Besides,only six Hall-effect latches,half of which were backups,were used to control commutation and measure the speed with improved M/T algorithm.IP cores and system level ASIC of the full-dig... |
