The electro-hydraulic servo position synchronization control system of hydraulic cylinders is prone to internal and external interference, which results in the inconsistent positioning of the cylinders. To address this issue, a mathematical model of the hydraulic cylinder’s electro-hydraulic servo control system was developed based on a test platform that synchronizes both cylinders’ positions. The “equivalent + master–slave” control mode was employed due to the drawbacks of “equivalent mode” and “master–slave mode” in engineering applications. An active disturbance rejection controller (ADRC) was designed, and a simulation model of synchronous active disturbance rejection control of both cylinders was created. The simulation results were compared to those of traditional PID control, revealing that the active disturbance rejection controller can more effectively enhance the system’s tracking performance and anti-interference capability while reducing the synchronization error.
