Error reduction of optoelectronic tracking platform for switching fromcompound control to feedback control

More Information
  • Control theory, simulation and experiment of EO system show that the tracking errors increase suddenly when the optoelectronic tracking platform switches the control mode from compound control to feedback control. To solve the problem, a constant compensation method was put forward. The method compensated the errors caused by the control mode switching and made the steady-state error state not increase after compensation, it decreased the tracking errors evidently. The simulation and experiment data prove the method is feasible.
