High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...

To address the issues that arise when auto-leveling vehicle body of a hillside tractor under complex working conditions, an control system was developed based on newly and four-point leveling mechanism. In this approach, accuracy stability were improved by adopting sliding mode variable structure algorithm fuzzy switching gain adjustment to achieve real-time dynamic control. obtain curves front...
