The invention relates to the technical field of data processing, and discloses an airborne photoelectric platform turning system. The airborne photoelectric platform turning system provided by the invention comprises a nonlinear controller, a selection switch, a current loop controller, a power driving element, a motor, a current feedback element, a speed feedback element, an angular position feedback element, a first error conversion processing unit, a position loop controller, a second error conversion processing unit and a speed loop controller. The airborne photoelectric platform can be rotated at a preset angle through a non-linear given value output by a non-linear controller, and due to the fact that large overshoot can be generated by using the non-linear given value and the requirement for fast turning stability is not facilitated, a second phase current is determined through a speed loop controller and a position loop controller, so that the speed of the airborne photoelectric platform is adjusted. And the motor is controlled by adopting the second phase current of the closed-loop phase, so that the airborne photoelectric platform rotates to a 180-degree position, the overshoot of rapid turning is reduced, and the 180-degree rapid turning of the airborne photoelectric platform is realized.
本申请涉及数据处理技术领域,揭示了一种机载光电平台调转系统,所述系统包括:本发明提出的机载光电平台调转系统包括:非线性控制器、选择开关、电流环控制器、功率驱动元件、电机、电流反馈元件、速度反馈元件、角位置反馈元件、第一误差变换处理单元、位置环控制器、第二误差变换处理单元、速度环控制器。能够通过非线性控制器输出的非线性给定值,先将机载光电平台完成预设角度的旋转,由于利用非线性给定值会产生大的超调,不利于快速调转平稳性的要求,故而通过速度环控制器、位置环控制器,确定第二相电流,并采用闭环相第二相电流对电机进行控制,使机载光电平台旋转至180度的位置,减少快速调转的超调量,从而实现机载光电平台的180°快速调转。
