| Abstract:Aiming at the problems of slow speed and poor universality in cross-platform joint-simulation of existing guide vane servo
system model, a general modeling method of guide vane servo system based on dynamic characteristic equations with strong component uni?
versality was proposed. Using the component modeling method, from the bottom-level equations to the component-level models, and then
to the top-level system, a hierarchical and modular modeling architecture was established, which organically integrates principles with engi?
neering applications. By analyzing the working mechanism of each component of the guide vane servo system, an AMESIM model of the
guide vane servo system was established, and the dynamic characteristic equation of each component was derived. A Simulink component
model library was developed, in which the component models were verified by comparing with the AMESIM models, finally, a Simulink
mechanism model of the guide vane servo system was constructed. The results show that the steady-state error is less than 0.12%, and the
slope response tracking error is 3.7%. For different frequency sinusoidal command signals with an amplitude of 5% of the actuator displace?
ment, the bandwidth of the guide vane servo closed-loop system is not less than 8 Hz. The guide vane servo system model has good accura?
cy, stability, and dynamic characteristics, indicating that the modeling method is feasible and effective. The advantages of the method in
cross-platform multi-disciplinary joint-simulation broaden its application prospects. |
