摘　　要：采用高性能32位DSP TMS320LF2812,以速率光纤陀螺和水平倾角仪为传感器,研究位置环+速度环的双闭环舰载天线稳定平台控制器;针对舰船主桅杆顶的大振动、强冲击以及长天线倒单摆式惯量负载等干扰跟踪精度因素,在速度环,设计一种PID和模糊控制的多模结构复合型控制方案;在平台上安装倒单摆式仿制天线进行实验,实验结果表明该稳定平台控制器的动、静态特性很好,稳定隔离精度小于1°。This stabilized platform controller based on high--competence digital signal processor TMS320LF2812 adopts double closed-- loops control structure, which uses rate fiber--optic gyroscope and gradienter as the sensors. An PID＋fuzzy complex controller in gyro sta- ble 10015 is proposed for the servo system with nonlinear property factors. Doing the experiment on the platform mounted inverted pendulum antenna. The result indicates that the proposed controller has good dynamic and static characteristics and is proved to be effective in bating carrier disturbance.
