Recent development in power electronics and soft computing techniques made it possible to design and implement the sophisticated control strategies of AC motor drives. In this paper the Direct Torque Control (DTC) which is one of the most excellent control strategies of ac motors which give very good steady and dynamic response is simulated. The current(More)
This study aims at developing a non-contact method for measuring the grinding wheel loading and wheel wear and thereby determining the optimum dressing intervals. With the aid of a machine vision system, this paper presents a systematic process for measuring the wheel loading. The images of the grinding wheel have been taken using a digital camera. These(More)
Vibrational energy is available from structures such as bridges and in many industrial and automotive scenarios and this had led to the development of novel Energy scavenging technique, that is introduced to harness ambient energy from the vibrations. Design of vibration energy harvester is done through Polypower films that act as intelligent elastics, as(More)
Mems based implantable drug delivery and minimally invasive systems are currently used for regular monitoring of cardiac energy balance. Here we have proposed a novel system for measuring intracardiac bio-impedance and application of Mems piezoelectric diaphragms actuates the micro pump and injects the drug using micro needle. Pressure gradients across(More)
