Quantitative Performance Modeling and Evaluation for Servo Control Systems Based on F-AHP

It is difficult to acquire quantitative performance evaluation result of servo control system with high precision and complex indexes, so the fuzzy analytic hierarchy process (F-AHP) is applied to quantitatively evaluate the performance of servo control system. Firstly the evaluation model with multi layers and indexes are founded, then the evaluation principle based on F-AHP is researched which is made up of model, determination for weights, calculation of membership and comprehensive evaluation. Analysis and experiments with actual data of electro-hydraulic servo test system has showed that the quantitative performance scores of servo control system can be obtained successfully by means of F-AHP, and the evaluation principle based on F-AHP is applicable not only to servo control system but also to other complex systems
