Pose estimation is one of the vital issues in mobile robot navigation. Odometry data can be fused with absolute position measurements to provide better and more reliable pose estimation. This paper deals with the determination of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of parameters namely weight, velocity, wheel p...

manufacturer has produced tapered, more flexible guidewires that straighten arterial contours less and push the burr into the edge of a curve less forcefully. The distal 9 cm of the drive shaft tubing was removed, also making the shaft more flexible. With evolution of the shaft-guidewire system biased cutting is reduced. However, in severely angulated segments such as the takeoff of a left circ...

A typical passive magnetic bearing has been modeled and analyzed for its performance characteristics. The magnetic bearing studied in this work comprised of a Shaft, inner magnets sleeved over the shaft, and outer magnetic rings. A detailed analysis has been perform on the force exerted by a permanent magnet on the shaft nurture to restore the shaft to its equilibrium position when an eccentric...

It is very common to use Variable Frequency Drive (VFD) with Induction Motor (IM) in Industry due to its numerous advantages. The advance of power electronics technology has also facilitated mass utilization of this combination. However, the application of IM with VFD may affect the actual design, performance and reliability of IM. When small and medium size motors are improperly used with VFD’...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...

51 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd.  Abstract— The development of advanced motor drive has been increases rapidly, because of their higher performance and reliability. The Sensorless control of permanent magnet brushless DC motor is presented in this paper. The fuzzy PI controller is developed for controlling the speed of the PMBLDC motor drive....

In many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. The hollow shafts made of functionally graded materials (FGMs) are such kind of compositions which were studied in this paper. Cylindrical FG shafts are composed of ceramic and metallic parts with power function distribution across the radial direction. The ceramic phase is isotropic elastic and th...

A validated dynamic model of a golf driver can be an invaluable asset in designing a well performing club. We present a model for simulating the golf drive that includes experimentally-measured inputs from actual golfers, and a three-dimensional (3D) flexible shaft model based on Rayleigh beam theory. The result is a computationally-efficient dynamic model that includes the “signature” of an in...
