Abstract: In order to acquire the comprehensive performance of the electro-hydraulic actuator,the fuzzy analytic hierarchy process(F-AHP) is applied to comprehensively evaluate the actuator's performance.The evaluating indicator architecture is established firstly,then the working principle of F-AHP is analyzed.The specific evaluation process based on F-AHP is applied with the actual testing data of a actuator.Experiment data shows that F-AHP can quantize the comprehensive performance,and the method is not only valid to the evaluation for the performance of the electro-hydraulic actuator,but also valid to other complex weapon systems.
