This paper proposes an adaptive neurofuzzy interface system ANFIS approach to identify the real power transfer between generators. Based on solved load flow results, it first uses modified nodal equation method MNE to determine real power contribution from each generator to loads. Then the results of MNE method and load flow information are utilized to train the designed ANFIS. It also incorpor...
In this paper river stage discharge models using Adaptive NeuroFuzzy Inference System (ANFIS) and Linear Multiple Regression (MLR) methods have been developed. This paper also investigates the best model to forecast river discharge. From the literature it is clear that ANN models and Fuzzy logic models are quite applicable on river stage discharge modelling. Hence this present study carried out...
ربات زیرآبی فصل مشترکی بین علم رباتیک و مهندسی اقیانوس میباشد و کاربردهایی نظیر بازرسی محیطی، نقشه برداری اقیانوسی و کاوش در اعماق آب ها را دارد. در این پژوهش حرکت یک ربات زیرآبی توسط سیستم کنترلی anfis و الگوریتم ممتیک هدایت و کنترل می گردد. منظور از کنترل در این نوشتار ردیابی مسیر می باشد. الگوریتم ممتیک، نوعی الگوریتم تکاملی می باشد که برای بهینه سازی یک مسئله، از روش ترکیب جستجوهای محلی با ...
In this study, three robust predicting methods, namely artificial neural network (ANN), adaptive neuro fuzzy inference system (ANFIS) and support vector machine (SVM) were used for computing the resonant frequency of A-shaped compact microstrip antennas (ACMAs) operating at UHF band. Firstly, the resonant frequencies of 144 ACMAs with various dimensions and electrical parameters were simulated ...
Optical character recognition (OCR) is becoming a powerful tool in the field of Character Recognition, now a days. In the existing globalized environment, OCR can play a vital role in different application fields. Basically, OCR technique converts images into editable format. This technique converts images in the form of documents such as we can edit, modify and store data more safely for long ...
This paper presents the design of the hybrid PID-ANFIS controller for controlling the speed of the Brushless Direct Current Motor (BLDCM). The objective of this work is to obtain the BLDCM speed controller equipment effectively. The hybrid PID-ANFIS controller is a combination of classical PID controller and ANFIS controller. This method is applied to BLDCM speed controller by simulation and im...
عملگرهای پیزوالکتریک بدلیل دقت بالا، پاسخ سریع و هزینه کم پیزوسرامیک ها استفاده ی گسترده ای در ابزارهای دقیق مانند میکروسکپ های نیروی اتمی، دستگاه های نوری (optic)، صنعت پزشکی در انبرهای جراحی، صنعت هوانوردی و موقعیت یابی میکرو و نانو دارند. این عملگرها براساس اثر معکوس پیزوالکتریک کار می کنند. با اعمال یک جریان و یا ولتاژ الکتریکی به ماده پیزوالکتریک ، تنش و در نتیجه تغییر شکل در ماده ایجاد می...
In this study, a new approach based on adaptive neuro-fuzzy inference system (ANFIS) was presented for detection of electrocardiographic changes in patients with partial epilepsy. Decision making was performed in two stages: feature extraction using the wavelet transform (WT) and the ANFIS trained with the backpropagation gradient descent method in combination with the least squares method. Two...
Abstract Electroencephagram (EEG) is the recording of electrical activity of the brain. Though it is intended to record cerebral signals,it also records the signals that are not of cerebral origin called artifacts. Artifact removal from EEG signals is essential for better diagnosis. This paper proposes a hybrid learning algorithm based on Adaptive Neuro-Fuzzy Inference System (ANFIS) for elimin...
This paper proposes an Adaptive Neuro-Fuzzy Inference System (ANFIS) for predicting the surface roughness in turning operation for set of given cutting parameters, namely cutting speed, feed rate and depth of cut. Two different membership functions, triangular and bell shaped, were adopted during the training process of ANFIS in order to compare the prediction accuracy of surface roughness by t...
