摘要
为了实现船只在海上航行时卫星天线平台的稳定工作,设计了方位轴伺服控制系统。天线系统主要由无刷直流电机、天线组、GPS定位系统、航向角传感器、角度编码器和角速率传感器(即陀螺仪)等组成。根据系统工作原理,以一个自由度为例,通过角度环和角速度环的双闭环动态设计实现系统;最后,利用MATLAB语言进行仿真实验。结果系统的超调量和跟随性能良好,能满足设计要求。在实际应用中,可以扩展到三个自由度,用于在船舶以及其他外界波动较大的场合,以实现工作平台的稳定。
In order to realize the steady work of the satellite while the ship sailing at sea, have designed the servo control system of the azimuth axle. The system is compose of Brush-less DC Motor, an aerial, GPS navigation system, heading angle sensor, angle encoder and sensor of speed of angle (namely gyroscope), etc. Used the working principle of system, as one freedom of motion for example, through the dynamic design of the double closed loop that compose of the angle loop and the angle speed loop to realize steady work of system. Finally, utilize MATLAB language to carry on digital emulation. The result is the overshoot and follow performance of the system are good, so could meet designing requirement. In practical application, can expand to three freedom of motion in ship and other occasion such as big fluctuating.
