Abstract:An “Automatic Power Generation Vehicle (APGs)”, is a vehicle which relies not only on batteries but also an wind energy which drives the turbine blades and rotates the generator which produces electric current. It has greater advantage over electric vehicle in which the battery needs to be recharged again and again in a short period of time. Our objective is to design an APG that is initially powered by battery and after that while in running condition the vehicle is powered by the wind turbine. It provides an advantage that there is no environmental pollution and no need of charging the battery frequently. APG vehicle increases the efficiency with the help of wind energy thereby achieving better performance and economy. Electric vehicle is powered by battery alone is not suitable for long journey because its need frequent charging for the battery. Thus APG vehicle is best suited for urban and rural travel.

Abstract: The certain set of circuit parameters can generate chaotic waveforms in Colpitts Oscillators. Regarding possible application to chaos-based communications the problem of mutual synchronization eventually arises in the Colpitts generators. We present the results of, experimental investigation of synchronization between two identical Colpitts generators. The method of linear difference signal has been applied.

Abstract:The magnetic compass has been guiding travelers for thousand years or more. It is one of the oldest and easiest navigation instrument used to determine heading. Using earth’s magnetic field, electronic compass based on Anisotropic Magneto resistive (AMR) sensors can sense and electrically resolve the heading with enhanced accuracy.  The core errors of magnetic sensor: hard and soft iron errors are determined and corrected.  Magnetic field at two positions, direction between them based on two sensor values are found. Scaling factor is verified from the world magnetic field map. Calibration algorithm is developed for the same from least square optimization method to get accurate heading.

Keywords:  Compass, Calibration, hard iron error, heading, Magnetoresistive, soft iron error.

Abstract:This paper presents the importance of soft computing techniques in Wind Generation System. Since wind speeds typically vary over a wide range, the turbine speed needs to be continuously adjusted so that its power output can be maximized and also it usually leads to better result than those of the conventional controllers. Many researchers have studied and performed the simulations in wind generation system using different soft computing technique. The purpose of the study is to do comparisons of various soft computing techniques used for improvement of wind form model. In wind generation system different techniques like particle swarm optimization, generalized regression neural network (GRNN), fuzzy logic control, genetic algorithm, mean variance optimization algorithm etc. has been used for efficiency optimization and performance enhancement control. The characteristics and merits of these techniques on wind form model is then compared and studied. After studying the different soft computing technique it is found that a system using the fuzzy controller based amongst the other soft computing techniques shows more accurate control performances.
