电视导引头伺服稳定平台数字控制器的研制

Design of the Digital Controller for Servo Stabilized Tracking Platform in TV Guidance Seeker

针对电视导引头系统对快速性要求高的特性,设计了一种基于DSP的高速数字控制器。以CCD摄像机作为位置环反馈传感器,以液浮式速率陀螺作为速度环反馈传感器,采用随动平台速率陀螺稳定方案的伺服稳定跟踪平台结构,给出了伺服控制器的软硬件设计,分析了针对该系统的双环PID控制算法的设计及调试方法。实验结果表明,该控制器动静态性能良好,可满足系统的要求。

Aimming at the TV guidance seeker characteristic,a high speed digital controller based on DSP is designed.The constitution of the servo stabilized tracking platform is presented by using adopts CCD vidicon as position closed-loop sensor and gyro as rate closed-loop sensor.The hardware and software design of the platform controller is given.The double closed-loop control-method is discussed in details. The experimental results show that both of static and dynamic performances of the controller are good.
