摘要
导弹伺服系统是包含机械、电气、电磁、控制等多物理场的复杂机电系统.针对传统理想线性仿真技术存在的模型颗粒度不够、仿真精度不高的问题,开展细颗粒度多物理场仿真技术研究.对伺服系统的伺服电机、电路、控制算法、传动机构进行精确物理场建模,然后采用基于VHDL-AMS的统一语言建模技术、模型降阶技术和联合仿真技术相结合,实现伺服系统集成化多物理场仿真.仿真结果和样机试验结果对比表明:模型颗粒度高,仿真精度可达到87%.通过该方法可对系统进行高精度、高保真度的虚拟验证,降低研制风险.
Abstract
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.
