This paper explores the dynamic modeling of a novel two stage bidirectional poppet valve and proposes a control scheme that uses a Nodal Link Perceptron Network (NLPN). The dynamic nonlinear mathematical model of this Electro-Hydraulic Control Valve (EHCV) is based on the analysis of the interactions among its mechanical, hydraulic, and electromagnetic subsystems. A discussion on experimental approaches to determine the model parameters is included along with model validation results. Finally, the control scheme is developed by proposing that the states of the EHCV follow a set of desired states, which are calculated based upon the desired valve flow conductance coefficient KV. A simulation is presented at the end to verify the proposed control scheme.

A new type of substrate structure Electronic Enhance Collector IGBT (EEC-IGBT) was proposed, and the working principle was introduced in this paper. Compared with conventional IGBT, the substrate of EEC-IGBT was divided by the groove structure composed of oxide and aluminum. Finally, simulation analysis about the EEC-IGBT performance influence by structural parameters was given. The simulation results showed that the turn-off loss of EEC-IGBT was reduced 30% compared with CS-IGBT in the same condition voltage.

The Stability

In this article, the tamper system of multifunction- paver has been simulated by AMESim, and the simulation model of the tamper system of multifunction- paver has been established. The simulation results show that the hydraulic impact of the system will be decreased and the response speed of the system will be improved, when accumulator and PID controller are equipped. Simultaneously, the stability of vibrated system will go down with the increase of vibration frequency. When vibration frequency is over 20 HZ, the performance of system will go bad, and the vibration of system will be significantly enhanced.

In this contribution, measurement data of phase, neutral, and ground currents from real low voltage (LV) feeders in Germany is presented and analyzed. The data obtained is used to review and evaluate common modeling approaches for LV systems. An alternative modeling approach for detailed cable and ground modeling, which allows for the consideration of typical German LV earthing conditions and asymmetrical cable design, is proposed. Further, analytical calculation methods for model parameters are described and compared to laboratory measurement results of real LV cables. The models are then evaluated in terms of parameter sensitivity and parameter relevance, focusing on the influence of conventionally performed simplifications, such as neglecting house junction cables, shunt admittances, or temperature dependencies. By comparing measurement data from a real LV feeder to simulation results, the proposed modeling approach is validated.
