摘　　要：导弹控制系统中舵机是关键部分,其内部功率放大组件的性能影响着导弹的飞行状态。而在以SA03功率放大器为核心的舵机系统进行性能检测过程中,目前仍采用的传统人工检测方法不仅效率低,操作复杂,尤其在人工插拔切换电阻调节饱和电压环节,不仅费时且极易对电路板造成损伤。为满足舵机放大器在批量性能质检过程中的自动化测试需求,基于Lab Windows/CVI平台,设计了一款舵机放大器性能参数自动检测系统,可以同时对4台舵机放大器及其相关驱动控制电路进行性能评估检测。该系统可以为待测产品供电及控制信号输入的同时,进行测试指标的数据采集、处理、判读和电子化存储等,针对饱和电压的检测利用可编程电阻进行连续调节解决现存问题。应用结果表明,该系统操作简便,测试效果良好,满足舵机放大器自动化测试的要求,设计的可编程电阻可提供1 666.5 kΩ以内的电阻输出,分辨率为0.1 k且精度在0.15%以内。The steering gear is the key part of the missile control system,and the performance of its internal power amplifier components affects the flight state of the missile.However,in the performance detection process of the steering gear system with SA03 power amplifier as the core,the traditional manual detection method is not only low efficiency,complex operation,especially in the manual plug and switch resistance to adjust the saturation voltage,not only time-consuming and easy to cause damage to the circuit board.In order to meet the requirements of automatic testing of steering gear amplifier in batch performance inspection process,based on Lab Windows/CVI platform,this paper designed an automatic testing system for performance parameters of steering gear amplifier,which can simultaneously evaluate and test the performance of four steering gear amplifiers and their related drive and control circuits.The system can provide power supply and control signal input for the product to be tested at the same time,the data acquisition,processing,interpretation and electronic storage of test indicators,For the detection of saturation voltage,the programmable resistor is used for continuous adjustment to solve the existing problems.The application results show that the system is easy to operate and has good test effect.The designed programmable resistor can provide resistance output within 1 666.5 kΩ,the resolution is 0.1 k and the accuracy is less than 0.15%.
