摘　　要：双轴稳定平台可以隔离舰船摇摆对舰载天线通信质量的影响;在研究平台隔离舰船运动原理的基础上,提出了一种电机转矩环,陀螺速度环和平台位置环的三闭环伺服控制器;其中电机转矩环提高了电机输出转矩的线性度;陀螺速度环利用光纤陀螺仪作为速度反馈传感器来构成稳定平台系统在惯性空间速度闭环,采用Fuzzy+PID控制相结合的复合控制策略,有效隔离舰船运动对平台姿态的影响;配合由二维水平倾角仪作为位置传感器的平台位置闭环,构成双轴稳定平台伺服控制系统;系统联调测试结果表明,系统稳定精度在1°以内,满足设计指标和精度要求,且系统动、静态性能良好。In this paper, the structure of a 2--axis stabilized platform for ship borne antenna is introduced, which isolate the Antenna from the disturbance and vibration of the ship. Based on the analysis of the isolate principle, a novel triple--close--loop servo control system was proposed. The first loop which could improve the linearity of the torque export is called motor torque loop. The middle loop, gyro speed loop, the core of the servo control system which used fiber optic gyro as an inertial sensor and used a PID ＋ Fuzzy multiple control algorithm, could be effective on isolation of the disturbance. The third loop is platform position loop which used a gradienter as a sensor. The experimental results prove that the triple--close--loop servo control system provides good steady--state performance and quick dynamic re sponse.
