This paper presents Permanent Magnet Synchronous generator (PMSG) based a variable speed wind turbine systems including energy capacitor system (ECS). The ECS is the combination of electric double layer capacitor (EDLC) known as supercapacitor and power electronic devices for wind power application with its detailed modeling and control strategy which can supply smooth electrical power to the power...
It is very important to stable the grid connected wind farms output power. This paper presents a fixed speed wind turbine based Induction generator (IG) including energy capacitor system (ECS) which is the combination of power electronics and electric double layer capacitor (EDLC). It is seen that ECS can significantly compensate voltage and power fluctuations of grid-connected fixed-speed wind generator...
Non invasive and continuous measurement of blood pressure becomes popular now a day. This is very effective way for hypertensive patients to prevent cardiovascular problems and precisely regulate anti-hypertension cures. Blood pressure can be measured by conventional cuff-based sphygmomanometer or invasive instruments in non continuous mode. In this paper, we propose the microcontroller based continuous...
This paper focuses on the automatic tracking of a moving object. The motion of living beings such as human beings, cats, dogs, fishes or any other substances like star, earth, and airplane can be tracked by this system. A tracking algorithm is developed in order to analyse the motion of object is chaotic or not. Automatic tracking of object is done by several stages. These are image capturing, image...
Electronic energy meter is capable of taking readings and can store it into its memory. Taking energy meter reading is time consuming and an expensive task. The meter reader travels for a long distance and take the reading manually to prepare the bill. Consumers have to go to the billing office, stand in a long line and submit the bill. This is a boring job and time consuming also. It can be avoided...
This paper represents the microcontroller based modified sine wave (MSW) generator for power inverter which is connected to the PV (Photovoltaic) system. The advantage of this inverter is the use of a low cost microcontroller that generates MSW having low harmonics and voltage regulation is fully controlled by microcontroller only which is approximately zero. It can also vary the frequency of inverter...
Non invasive continuous blood pressure measurement system is more useful than conventional blood pressure measurement systems. The arterial system is extraordinarily well regulated blood delivery network in human body. It responds very quickly according to the body movements like altered body position, or in sudden excitation. So now a day's continuous blood pressure monitoring devices are becoming...
Aim of this paper is to develop yaw and roll vehicle model and active steering control preventing rollover. Selecting the center of gravity of the vehicle's sprung mass; an active control which is a function of certain parameters is designed. Stability augmentation control, emergency steering control and emergency braking control are three feedback loops. An auxiliary steering angle from stability...
