Active Disturbance Rejection Control for Random Signal Tracking in Electro-Optical Tracking Systems Based on Random Sensitivity Function

The target trajectory tracked by the electro-optical tracking system (ETS) is often accompanied by randomness, while the tracking effect of the active disturbance rejection control (ADRC) on the random signal in it lacks a targeted evaluation index. To address this problem, a random sensitivity function evaluation indicator based on the framework of ADRC is introduced. The random sensitivity function is introduced according to the two-degree-freedom structure of ADRC, and three frequency-domain indicators are utilized to describe the steady state performance and dynamic performance of the ADRC in the ETS in the tracking process of random reference signals. Finally, the effectiveness of the proposed indicators are verified using simulation analysis.
