In this paper, a second order transfer function of a single-axis PZT nanopositioner stage (P-752.21C) is identified around an operating point. The nonlinearity due to the hysteresis is modeled using look-up tables. The validation of the complete model is achieved experimentally. Two control approaches are developed. The former is a PI controller where the control parameters are tuned using Ziegler-Nichols...
This paper presents the robust of Sliding Mode Controller according to parameters change and worst signal noise. Mathematical procedure for calculating the values of the gains of Sliding Mode Controller (SMC) and equation of Sliding Mode (slopes)parameters are determined. The proposed control scheme is derived, simulated and results obtained SMC by using MATLAB Version 7.10.0.499 (R2010a) Simulink,...
In this paper a new architecture to calculate Ln function based on data-oriented theory is introduced. Because of using proper and huge amount of data in modeling, implementing of this type of models causes less calculation complexity. Data-oriented architecture is made of considering memory and small calculation unit together. Proposed method calculates Ln function faster than common methods.
Developing correct and complete real-world software applications is a difficult task in terms of the number and flexibility of the essential components and their interrelationship. As the field of agent-based computing matures, the requirements of well-founded techniques and methodology for such systems modeling will increased. This paper used integration of two well known modeling techniques, X-machines...
The CoMSON project is a distributed European research project that combines research efforts from both academia and industry. This project is distributed among eight institutions across Europe. The aim of this project is to implement an experimental simulation platform (in software code) for devices in micro and nano-electronics with an integrated e-learning system. This project has two main goals...
This paper covers the design of electrical model of Sierpenski fractal antenna. The proposed model is based on the electrical model of triangular patch. Each elementary triangle of Sierpenski patch is replaced by its model and then the whole model is built. The return loss of the model is compared to both a physical patch and another electrical model. The proposed model has the same resonant frequency...
The expansion of new technologies and the World Wide Web is having a tremendous impact in education. Today technology is used as a teaching aid as well as an educational management tool. These trends are making e-learning an indispensable teaching and learning tool, replacing in some cases more traditional teaching methods. One of the issues normally encountered in the implementation of new courses,...
