Abstract EN
Customary disturbance rejection in the photoelectrical platform is “passive,” which makes it difficult to further improve the isolation degree owning to the strict restriction of mechanical resonance frequency.
In this paper, a booting-type ADRC is proposed, whose disturbance estimation process is guided by target value to reduce the overshoot and lag in the estimated value of disturbance.
All kinds of disturbance in the system are modeled in a unified way by using the equivalent disturbance voltage to avoid the complex modeling process.
Based on the simplified model, extended state observer (ESO) is designed to realize a real-time estimation of the disturbance.
Then, the disturbance compensation is added to generate the final control value by combining the customary square lead-lag controller.
Experiments are implemented to test the proposed control strategy by mounting the photoelectrical platform on a flight simulator and generating a motion perturbation.
Compared with the case of only traditional lead-lag controller, the isolation degree of disturbance is enhanced obviously.
And the experiments also illustrate strong robustness of ADRC.
