Omni-directional wheeled motion system with its flexible steering, stable structure and reliable control precision, become the basis of the mobile robot system which used indoor. In this paper two kinds of Omni-directions platform which wheeled by three Mecanum wheels are built up, by setting up the dynamical simulations about the two model based in simulation software, and according to the dynamic...
The design of PWM sliding mode control for a novel frequency conversion circuit which called boost matrix converter is presented. The general situation of sliding mode control strategy and frequency converters are firstly introduced. The specific analysis of boost matrix converter and the derivation process of PWM sliding mode controller are clarified afterwards. Finally the system simulation result...
In many fields including digital image processing and artificial retina design, they always confront a balance issue among real-time, accuracy, computing load, power consumption and other factors. It is difficult to achieve an optimal balance among these conflicting requirements. However, human retina can balance these conflicting requirements very well. It can efficiently and economically accomplish...
This paper reports the design considerations, simulation results and test specifications of an S-band, 70 MHz bandwidth, 50 kW average power klystron, which was developed by the Institute of Electronics, Chinese Academy of Sciences (IECAS) before August, 2007. The representative result is 56 kW average output power under the conditions of 89 mus RF pulse width, 300 Hz repetition rate, and continuous...
