This paper aims at investigating the use of an induction wound rotor motor to generate voltage instead of the old diesel engines that are still used in many factories, like old cement factories, in Jordan. In this investigation, a simulation model of induction wound rotor motor was implemented using Matlab/Simulink. The excitation dc current was connected to a two-phase rotor circuit, and the voltage-current performance characteristics were investigated and evaluated under different load types. The simulation results confirmed the possibility of using the induction wound rotor motor as a synchronous generator.

Two Sides

The driving theory and the dynamic characteristics of small radius steering, medium radius steering and big radius steering is analyzed, and the simulation model is established under Matlab/Simulink. Then the track bulldozers steering performance of the three sheerings is simulated. The results show that, at different steering modes, the running states of the two sides driving motors are not the same, and the track driving forces of the two sides vary widely. The track driving force is great in the small radius steering model, while small in the medium and big radius steering models. The simulation results lay the foundation for dual-motor drive track bulldozers steering performance matching.

This paper presents the design and modelling of a new powered ankle prosthesis which combines electrohydrostatic actuation with a controllable passive damper. The new powered ankle prosthesis can switch quickly between passive mode and powered assistance mode, and is intended to just give assistance at certain points within the gait cycles, such as during toe push-off. The design concept and a prototype built to demonstrate the concept are presented. A simulation model was developed to help analyse the performance characteristics. The structure and parameterisation of the simulation model are described. A comparison between simulation results and experiment results is undertaken in order to validate the model and assist in the optimisation of the design. Some results from an initial trial with amputees are included in the paper. According to subjective feedback from the amputees, the new powered ankle prosthesis provides sufficient force at push-off to assist with walking. Future investigations will be focusing on the compactness, weight reduction and control of the powered ankle prosthesis.

In order to reduce the common-mode voltage (CMV) for three-to-five-phase indirect matrix converter (IMC), the CMV with the conventional modulation strategy is analyzed. A novel carrier-based PWM (CBPWM) method is proposed in this paper. The zero vectors in the inverter stage are assigned to the rectifier stage, equivalently, which are not considered in the inverter stage. The zero vectors are selected appropriately to ensure that the dc-link is connected to an input phase with the minimum absolute value, so that the larger CMV can be avoided. Then, the modulation signals are derived by the duty ratios, which are used to compare with the only one carrier signal and generate the gate pulses of switches. With the proposed method, the CMV is reduced effectively compared with the conventional modulation strategy. This method is analyzed and researched with a simulation model established by Matlab/Simulink. Simulation results are provided in detail to verify the feasibility and validity of the proposed method.
