I am developing a Simscape model for the Moog 30 two-stage servo valve and need to identify critical parameters for accurate simulation. My goal is to achieve a model that closely represents the real valve's behavior.Challenges & Questions:
Parameter Identification:
- What is the best approach to determine the values for the following parameters?
- Mechanical Properties: Armature Mass, Armature Damper, Armature Hard Stop, Spool Mass, Spool Damper
- Fluid Dynamics: Flapper Spring, Flapper Damper, Nozzle A, Nozzle B, Fixed Orifice A, Fixed Orifice B
- Orifices & Hydraulic Forces: Orifice AT, Orifice PA, Orifice PB, Orifice BT (each consisting of Orifice and Spool Orifice Hydraulic Force)
- Are there standard values available for these parameters, or do they require experimental calibration?
Estimation Strategies:
- If direct values are unavailable, what are the recommended estimation techniques?
- How do researchers typically extract these parameters from experimental data or datasheets?
- Are there existing MATLAB tools (e.g., parameter estimation toolboxes, system identification methods) to help determine them?
Validation:
- What are the best methods to validate that the identified parameters correctly represent the servo valve’s real behavior?
- Would comparing simulated vs. experimental flow-pressure characteristics be sufficient?
- I am considering reaching out to MathWorks support, but I would appreciate insights from others who have faced similar challenges.
Any guidance on parameter identification, estimation methods, or best practices for Moog 30 servo valve modeling in Simscape would be highly appreciated!
