摘　　要：为适应弹载雷达导引头小型化低成本的发展需求,设计一款基于DSP串口扩展的多串口伺服控制器。通过开发DSP串口复用功能,在仅有3组SCI收发寄存器的硬件资源下,协同完成方位和俯仰角度、角速度3路传感器数据以及1路上位机数据的收发,实现了单DSP架构下的2维伺服控制系统设计。精简了FPGA相关电路和软件设计,为伺服控制器的低成本微小型化提供了技术支撑。实验结果表明:该系统工作可靠、性能稳定,适用于工程应用。In order to meet the development requirements of miniaturization and low cost of missile-borne radar seeker,a multi-serial port servo controller based on DSP serial port expansion is designed. Through the development of DSP serial port multiplexing function, the hardware resources of only three groups of SCI transceiver registers are used to complete the transceiver of three-way sensor data of azimuth and elevation angle, angular velocity and one-way host computer data,and the design of two-dimensional servo control system based on single DSP architecture is realized. The FPGA related circuit and software design are simplified, which provides technical support for the low cost and miniaturization of the servo controller. The experimental results show that the system is reliable, stable and suitable for engineering applications.
