【摘要】 为了得到高精度的航测相机伺服系统,为实际系统实现提供理论依据,对该伺服系统进行基于仿真的设计。首先对控制对象直流力矩电机进行了建模,然后完成整个伺服系统框架的搭建,采用多种控制策略完成电流环,速度环,位置环的校正设计,并针对陀螺稳定回路中引入的飞机姿态的变化加入了前馈控制补偿。最后通过系统仿真,得到了较好的动静态性能。更多还原

【Abstract】 In order to get high accuracy Aerial camera servo system and provide academic basis to implement of real system,we need design the servo system during simulation environment firstly.First,we build models of controlled object DC torque motor.Then,finish building the whole servo system,use multiform control methods to complete correction design of current-speed and position loop.And adopt feeddforward control to offset disturbance imported by gyro stabilized loop.At last,result of system simulation indicates that the designed system has good dynamic and static performance.更多还原
