This study emphasizes the use of type-2 fuzzy (T2-Fuzzy) to improve the adaptive proportional-integrative-derivative (PID) control in the lower extremities. Several problems were identified from previous studies and those were the slow achievement of the target angle and the presence of oscillation in the achievement of the target blade. The oscillation occurred as the consequence of deploying ...

Estimating the intention of space objects plays an important role in aircraft design, aviation safety, military and other fields, is reference basis for air situation analysis command decision-making. This paper studies estimation method based on fuzzy theory, combining probability to calculate between two objects. takes a object as origin coordinates, observes target’s distance, speed, relativ...

investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

one of the most important challenges in nonlinear, multi-input multi-output (mimo) and time variant systems (e.g., robot manipulator) is designing a controller with acceptable performance. this paper focused on design a new artificial non linear controller with on line tunable gain applied in the robot manipulator. the sliding mode fuzzy controller (smfc) was designed as 7 rules mamdani’s infer...

Quality function deployment (QFD) is a method used for the manufacturing process of a product or service that is devoted to transforming customer requirements (CRs) into appropriate engineering characteristics (ECs) by specifying the importance of the ECs and then setting their target values. Confronting the inherent vagueness or impreciseness in the QFD process, we embed the fuzzy set theory i...

To overcome this deficiency, a compound fuzzy neural network named IMJ was introduced which combines the process’s rule-based reasoning and function approximation functions. This paper presents the concept of target numbers, and introduces a number of recursive algorithm target issues. Suppose given positive integer n is A (1), A (2), ..., A (n-1), A (n), the need to find the corresponding numb...
