Study on Verification, Validation and Accreditation of Control and Guidance Simulation for Underwater Vehicle

论述了对水下航行器制导半实物仿真系统的校核、验证和确认 (verification、validation、accreditation ,VVA)技术研究的必要性 ,在论述VVA基本概念、归纳VVA主要方法的基础上 ,结合该仿真系统的特点 ,应用Theil’s不等式法、灰色关联度法和频谱分析法对航行器的数学模型进行了验证 ,结果表明该数学模型具有一定的可信度 ,并进一步提出了对该半实物仿真系统进行VV&A评估的 4个阶段和 7个主要步骤。

In this paper the importance of the study on verification, validation and accreditation (VV&A)techniques in the HIL simulation system for underwater vehicle is discussed. After the basic concepts and techniques of VVA are presented, a mathematical model of underwater vehicle is validated based on the characteristics of the HIL simulation system by using Theil's inequation, grey correlativity and spectrum analysis methods. The conclusion indicates the model is dependable in some degree. Then a general process including four stages and seven steps is discussed for the HIL simulation system.\;
