The paper presents aspects concerning the modeling, driving scenarios and control structures of two classes of vehicular power train systems with continuously variable transmission (CVT). The modeling includes an analysis of the systems' components which include the spark-ignition internal combustion engine, the torque converter, the continuously variable transmission and the wheels. The CVT offers...
The saving energy with train operation is more important than before from the view points of the global environment. However the energy saving design on the traction equipments sometimes has a trade off relation against the down sized and lighter weight traction equipments. In this paper, an optimizing method of the generic algorithm is applied to the numerical simulation to calculate the consuming...
In this research, an equation of motion of a WIP (Wheeled Inverted Pendulum) running on an irregular terrain such as the inclined road is derived. The WIP becomes a popular platform for mobile robots which should be running on not only regular pavement but also irregular terrain. In order for the WIP to run on those roads there requires a robust controller which can be achieved from a fine equation...
Dynamic parameters of a robot affect the performance of advanced control schemes significantly. In this study experiments to identify the dynamic parameters of AT2 robot are carried out. The excitation trajectory for identification is parameterized with Fourier series. The trajectory is optimized to minimize effects of uncertainty using condition number as the index. Recursive optimization is proposed...
Rotary eccentric loads often lead to vibration problems in motors, which may reduced their reliability and operating life. In order to reduce the radial vibration in permanent magnet motors, a real time detection method for rotary eccentric load based on the theoretical analysis of the motor vibration and the mechanical analysis was given, and a novel control strategy based on FOC (field oriented...
