Based on the theory of the mathematical model of induction motor, the model of induction motor vector control is proposed with the simulation toolkit of Matlab/Simulink, and the related sub-system modules are described in detail and the specific illustrations of the sub-system are also given. Take a simulation of the system, the results such as the(More)
Based on an analysis of error sources of industrial robots, we build a pose error model of industrial robots with screw theory, which overcomes the defect that the error on the y-axis could not be reflected by the classical D-H parameter method. Given the error sources which influence the end-executor's accuracy, we established a screw representation of the(More)
This paper puts forward a model of the seamless collaboration between human and industrial robot depending on the technology of using the electroencephalogram(EEG) to control the movement of industrial robots. Wavelet packet decomposition is operated on the EEG signals for analysis. EEG signal features that industrial robot motion control needs are(More)
This paper investigates the dynamics and control aspects of the linear motion of a pendulum-driven spherical rolling robot. The dynamic model is deduced for the linear motion of a spherical robot by using the Euler-Lagrange formulation. By appropriate definitions the equations of motion for the robotic system are transformed into the state space form. A(More)

An image segmentation fast method based on multi-scale belief propagation is proposed to solve the concrete CT image segmentations problem. Firstly, according to the feature of belief propagation algorithm, a self-characteristic multiscale belief propagation(MBP) is proposed; Then, according to compute complexity problem in process of belief messages(More)
In recent years, the research of concrete based on CT Images has been popular. A new modified Ray-casting on VTK aims to solve the poor effect on 3-D reconstruction of concrete CT image, which has great influence on the construction of accurate 3-D meso-concrete numerical model. Owing to this result, A new tech-VTK system came into being to get improvement(More)
Multi-dimensional modelling of the ow and combustion promises to become a useful optimisation tool for IC engine design. Currently, the total simulation time for an engine cycle is measured in weeks to months, thus preventing the routine use of CFD in the design process. Here, we shall describe three tools aimed at reducing the simulation time to less than(More)
