Validation of Torpedo Control System Simulation Models on Grey Relational Analysis

Grey relational analysis (GRA),as a comparison with numerical measure which cooperates the distance space with point-set topology, is very important in solving uncertain problems that with less data or data distribution unknown. Validation of simulation models is basic way to evaluate the credibility of simulation. Aiming at torpedo control system (TCS) simulation model's tactical indicators (TI) validation, method on time domain dynamic validation of TCS simulation model is studied. Without detailed model structure and just based on estimation of grey relational grade (GRG) between simulation data and actual sail data, credibility of TCS simulation models is proposed.
