The paper introduces the design of PWM Switching Power based on DSP control. It explains the implementation of PWM wave using the production of SPWM by DSP chip TMS320LF2407 as an instance. It is proved that the PWM Switching Power based on DSP technology has the character of fixing fast, distortion little, and small influence to the system by load's changing.

Kansei engineering has been found an effective methodology to deal with customers' feelings, demands and images of various products related with daily life. In this paper, the technique of Kansei engineering was applied to the research on the style of women's overcoats for the purpose of finding out the relationship between customers' feelings and design elements. Women's overcoats were chosen as research objects. By Card System, 6 word-pair were chosen to establish the semantic space. The product elements space, containing 7 items and 25 categories, was established by Shape Analytical Method. In the step of synthesis, the relationship between the two spaces was studied and quantified. Though regression analysis, some useful parameters were obtained, as R-Square, Category score and Range, and used to explain the reliability of the regression and influences of the each category and each item on perception judgment.

This paper is devoted to the tracking control problem of a permanent magnet stepper motor. A Lyapunov technique is performed to design a feedback law ensuring tracking of electrical and mechanical reference signals. It is shown that the speed is the only required measurement to implement the control law, avoiding any electrical quantities observer

This study aims to propose an approach that allows designing reconfigurable control for RMS. We propose an engineering approach that allows building modular controllers based on colored Petri nets. A key characteristic of our approach is the decoupling between extended operating sequences and transport system controllers. We also introduce the preallocation notion and the reconfigurability features of the control

The flight simulator is one kind of servo system with uncertainties and disturbances. To obtain high performance and good robustness for the flight simulator, we present a robust Backstepping controller based on a Disturbance Observer. Firstly, the design procedure of the robust Backstepping controller is described and correlative problems are proposed. Secondly, the principle and the design process of Disturbance Observer are analyzed and expatiated respectively. Finally, simulation results on the flight simulator show that the Disturbance Observer can compensate external disturbances including system input and output disturbance and the system performance can be improved. Therefore both robustness and high performance of the flight simulator are achieved. It is an applied technology for the control of servo system, such as the flight simulator.
