Multi-physical Field Modeling Design of Missile Servo System
Missile servo system is a complex electromechanical system containing mechanical,electrical,electromagnetic,control and other multi-physical fields.In response to the problems of insufficient model granularity and low simulation accuracy of traditional ideal linear simulation technology,the research of fine-grained multi-physical field simulation technology is carried out.The servo motor,circuit,control algorithm and transmission mechanism of the servo system are modeled with accurate physical fields,and then the VHDL-AMS based unified language modeling technology,model downscaling technology and co-simulation technology are combined to realize the integrated multi-physics field simulation of the servo system.The comparison of simulation re-sults and prototype test results shows that the model granularity is high and the simulation accuracy can reach 87%.The method can provide high precision and high fidelity virtual verification of the system and reduce the development risk.
