摘要
平台伺服系统是许多机载平台中一个重要的组成部分,特别是对于机载SAR(Synthesize Aperture Radar)而言,平台由于直接与天线相连接,它的工作状态将直接影响到最后的成像质量。以线性运算放大器件OPA2541为主,通过使用该功放模块的电压比较功能,产生驱动电动机工作的PWM,从而实现对平台直流伺服系统中电机的控制,实验表明,经过这种方法对平台进行驱动控制可以取得很好的效果,满足工程实践的要求。
Platform servo system is an important part for many airborne platforms, especially for the airborne SAR Because of the close connection between platform and antenna, the platform＇s working state is closely related with the final image quality. This paper will discuss how to use liner operational amplifier OPA2541＇s voltage comparing function to generate the demanded PWM signals which will drive electromotor to work well. The experiment results have showed that this usage of OPA2541 which proves well performance meets the project index demand.
