| 摘 要： | 磁场导向控制FOC（field-oriented control）矢量控制算法在伺服驱动控制系统中一般由CPU或DSP实现，难以满足航天应用中实时性较高场景下的需求。为提高宇航电机系统控制的实时性与可靠性，从FOC矢量控制算法的硬件加速角度出发，详细介绍了伺服控制器的设计，给出了一种全数字、高性能的伺服控制器硬件加速设计方案，并在具有可编程逻辑功能的宇航级SiP6117S芯片上进行了验证。仿真实验表明，相比于前人的设计，通过调整观测数据的量化精度来降低硬件加速过程中的处理延时，能有效改善多级流水延迟并在一定程度上提升算法的实时性。

| Abstract: | FOC vector control algorithm is usually implemented on CPU or DSP for servo driver control. It is difficult to meet the requirements of real-time scene in aerospace applications. In order to improve the real-time performance and reliability of aerospace servo driver system, we implemented the FOC vector control algorithm using hardware acceleration. The design of servo controller is introduced in details, and a hardware acceleration design scheme of full digital and high-performance servo controller is given. It is verified on aerospace grade SiP6117s chip with programmable logic function. The simulation experiments show that the performance of the servo driver controller is tested to verify the feasibility and effectiveness of the design. |
