This paper introduces a novel approach which uses a Hidden Markov Model (HMM) based Artificial Neural Networks (ANN) for prediction of systems that are non deterministic, dynamical and chaotic in nature. The HMM is used for shape based batch creation of training data, which is then processed one batch at a time by an ANN. The weights and Learning Rate of the ANN are tweaked to predict the correct output for an input dataset. The novel Prediction method used here exploits the Pattern Identification prowess of the HMM for batch selection and the ANNs of each batch to predict the output of the system. The Standard application of the Sun-Spot Data (SSD) was used for testing the competence of this method.

The rotor position is integrant information for vector control drive system of Permanent Magnet Synchronous Motor (PMSM). In this paper, the focus is on the rotor position of PMSM detecting by the resolver sensor. The outstanding features of this sensor are its robust structure and noise insensitivity. To extract speed from the output of resolver we need R/D demodulator circuit. A new Artificial Neural Network (ANN) Algorithm is proposed in this paper in substitution for R/D circuit and implemented in the vector control drive system of PMSM. The proposed scheme has been verified by simulation and experiment using MATLAB/Simulink.

In this paper, Quantitative Feedback Theory (QFT) based robust controller for AC-AC buck converter is proposed whose transfer function involves complex load term. The proposed design would give the robust control action against the uncertainty in the parameters of AC-AC buck converter and the desired specifications bound. The proposed design is illustrated using QFT-Terasoft toolbox.

Face detection is one of the challenging problems in image processing. A novel face detection system is presented in this paper and we propose a new approach using Takagi-Sugeno (T-S) fuzzy model and Hue Saturation and Value (HSV) color model. The algorithm uses fuzzy classifier in conjunction with HSV color model to quickly locate faces in the image. The fuzzy classifier basically examines small windows of an image to detect presence of faces in that window and the HSV color model detects the skin in the image. The algorithm is characterized by its simplicity and inexpensive computational requirements. The method shows that our system has comparable performance in terms of detection rates and false positive rates.

This paper deals speed control of a DC motor using fractional-order control. Fractional calculus provides novel and higher performance extensions for fractional order proportional integral and derivative (FOPID) controller. In this paper, the parameters of the FOPID controller are optimally learned by using Genetic Algorithm (GA), and the optimization performance target is chosen as the integral of the absolute error (IAE). Simulation results show that the FOPID controller performs better than the integer order PID controller.

The ECG signal is used for various medical diagnoses. For diagnosis purposes, the ECG signal must be free from the noise and undesired disturbances. In the present work the best algorithm for de-noising the ECG signal is identified using Discrete Wavelet Transform. Statistical analysis and comparison has been made to find the best wavelet function, their decomposition level and threshold selection method to be used for signal de-noising and thus improve the Signal to Noise Ratio.
