Abstract: The relevant parameters of the servo valve controlled motor device are not constant during its operation, and the identification of the parameters of the servo valve controlled motor device is conducive to the performance optimization of its hydraulic control system. Therefore, the research on parameter identification methods for servo valve controlled motor devices is of great significance. Firstly, the mathematical model of the servo valve controlled motor device is derived; Then, based on the mathematical model, a parameter identification method is proposed; Finally, taking a certain type of servo valve controlled motor device as an example, the time-varying curve of the relevant parameters of the device is obtained through simulation based on MATLAB software, so as to obtain the exact mathematical model of its control system within a certain work cycle, providing a reference for the implementation of control performance optimization strategies.
