The paper presents an algorithm which combining a neural network observer, it give more flexible and accurate control on the engine operation. In recent year, several researchers already proposed the algorithm which is based on a model-based adaptive control and uses artificial neural networks, and they assumed engine system is also controled by severe non-linear dynamics and their modelling. E...

This paper is concerned primarily with screw conveyors with fully enclosed tubular casings. The throughput, torque and power are significantly influenced by the vortex motion of the bulk solid being conveyed. The vortex motion, together with the degree of fill, govern the volumetric efficiency and, hence, the throughput. This, in turn, influences the torque, power and conveying efficiency. A th...

This paper presents a new dynamic walking controllers for quadrupedal robots with compliant legs. The algorithm implements a "walking bound" gait, (running bound without ight phase), requires only one actuator per leg at the hip, and commands a constant hip velocity during stance. The algorithm has been implemented successfully on our Scout II quadruped robot and has yielded stable walking for ...

A new type of motor that utilizes multilayer piezoelectric devices for electromechanical power conversion and mechanism of the strain wave gearing for generation of traveling motive force is proposed in this paper. The construction, basic operation, and torque generation mechanism of the motor are described. The motor can be operated in variable frequency. Experimental results on the prototype ...

A method of systematically controlling the rotational state of a sample levitated in a high vacuum using the photon pressure is described. A zirconium sphere was levitated in the high-temperature electrostatic levitator and it was rotated by irradiating it with a narrow beam of a high-power laser on a spot off the center of mass. While the laser beam heated the sample, it also rotated the sampl...

A new concept of the exoskeleton-type masterarm, composed of serial links, is introduced in this paper. To provide maximum range of human motion, several redundant joints are added to the serial links. In order to reduce the number of joints to be measured, kinematics of serial links was taken into consideration in design. Three measurable, controllable joints and three redundant free joints ar...

The observed braking index nobs which had been determined for a few young pulsars, had been found to differ from the expected value for a rotating magnetic dipole model. In addition, the observational jerk parameter, determined for two of these pulsars, disagrees with the theoretical prediction mobs = 15 in both cases. We propose a simple model able to account for these differences, based on a ...

The production of torque and pollutants of Variable Valve Actuation equipped internal combustion engines found in the automotive industry (both Diesel and gasoline engines) is studied. Variable Valve Actuation (VVA) is a technology which has been introduced to optimize engine efficiency at steady-states covering a wide range of operating conditions. In more details, the outcome of the internal ...

the intension in this work is to investigate the effect of different bending manifold pipes on engine performance for different engine speed. Power, Torque, and BSFC were calculated and presented to show the effect of varying bending pipes angles on them for all cases considered. A special program used to carry out the calculations. A simulation model for 4-cylinders spark ignition engine with ...
