摘　　要：为满足姿轨控火箭发动机快响应电磁阀的高精度脉冲控制需求,研制了一套基于虚拟仪器和PXI总线的脉冲控制系统。该系统选用成熟PXI总线硬件平台,设计可靠的电磁阀驱动电路,在LabVIEW图形化编程环境中完成控制软件的设计开发。经过全面的系统测试和验证后,控制系统多次应用于发动机地面试验中,表现出性能优良、可靠性高的特点,实现了快响应电磁阀的高精度脉冲控制。To meet the high-accuracy pulse control demands of fast response solenoid valves in an attitude and orbit control system, a pulse control system based on virtual instrument and PXI bus was developed. The mature hardware platform of PXI bus was adopted in the control system. The reliable drive circuit for solenoid valves was designed. Design and development of the control software were accomplished in the LabVIEW graphic programming environment. After comprehensive test and verification, the control system was used in rocket engine ground test for several times. The test result shows the system has excellent performance and high reliability, which achieves high-accuracy pulse control of fast response solenoid valves.
