Anti-interference high-precision rapid turning method of photoelectric system

The invention discloses an anti-interference high-precision rapid turning method for a photoelectric system. The method comprises the following steps: establishing a controlled object model; on a speed-position phase plane, an ideal bang-bang control switching equation is determined; under the condition that the stability of the system is guaranteed, turning control is conducted on the system through the maximum control torque, and according to the actual turning time and overshoot of the system, parameters of a bang-bang control switching equation are matched; designing a position loop PID controller and a speed loop sliding mode controller according to the controlled object model; selecting a position threshold value, and constructing a multi-mode controller; and the control module outputs a driving instruction to the driving module by adopting a multi-mode controller according to the input position instruction and the feedback angular position and angular velocity data, and finally, the anti-interference h
