non-destructive testing & evaluation methods are developed to inspect and investigate materialsand structures. ultrasonic testing is an ndt method can be used for measuring the thickness ofobjects, as one of its significant applications. the objective of this paper is designing and applyingan intelligent ut fuzzy control system for evaluating the thickness of thin metal objects in a rangeof...

this paper tries to determine efficiency of noise control method using fuzzy logic and based on collected data. from among various methods of noise control in workplace, sex methods (enclosure, installing noise absorber, enclosure and absorber, active, and administrative control, and personal protective equipment) were typically selected based on experts' judgment. for each of selected control ...

an asymptotically stable direct adaptive fuzzy pi sliding modecontroller is proposed for a class of nonlinear uncertain systems. in contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.moreover, a pi control structure is used to attenuate chattering. the approachis applied to stabilize an open-...

This article describes a fuzzy logic-based method optimized for the dome control of robotic astronomical observatory. A Mamdani inference has been developed in order to make decision open or close dome. The input variables are obtained from data received weather station besides percentage cloudy sky as derived by two allsky cameras. software tested at BOOTES-1 observatory part BOOTES Global Net...

direct yaw moment control systems (dyc) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the control yaw moment (cym). in order to achieve the superior control performance, intelligent usage of lateral forces is also required. the lateral wheel forces have an indirect effect on the cym and based upon their directions,...

This paper analyzes the number of operations and parameters of general fuzzy logic control algorithms. And limitations of loop controllers to implement the fuzzy logic control are investigated in terms of computation time and required memory. Using analysis of general fuzzy logic control algorithms, it is shown that general fuzzy logic control algorithms are not suitable for loop controllers. A...
