遥感卫星地面接收站伺服系统环路安全性设计

Security Design of Servo System Loop for Remote Sensing Satellite Ground Receiving Station

针对遥感卫星数据地面接收系统伺服环路设计中存在的安全问题,给出了伺服系统环路的安全性设计。当伺服系统环路出现异常时,通过对输入驱动指令箝位或去除、去除偏置指令,避免接收系统受到损坏,确保伺服控制的可靠性和安全性。该设计已用于相关工程项目中,使用结果表明该设计是合理可行的。

To solve the security problem in design of servo loop of remote sensing satellite data ground receiving system, a safety design scheme is provided for servo loop. When a fault should develop in either drive train, the design prevents damage to receiving system by clamping or removing the input driving commands and removing the bias command, and guarantees reliability and safety of the servo system. The application result shows that the design is reasonable and feasible.
