According to the requirements of a DC motor speed control system, a Dual-Closed-Loop Speed Regulator has been designed, with the AT89C51 and TMS320LF2407A is the MCU of this regulator. The function of TMS320LF2407A is sampling and regulating the speed of the DC motor, and the function of AT89C51 is inputting and displaying the speed of the DC motor. The hardware block diagram, program charts, and...
In this paper, based on passivity theory, coexistence of anti-synchronization and complete synchronization is found between two identical hyper chaotic Lu systems with different initial conditions. The passive controller is employed to make the error dynamical system not only passive but also asymptotically stable. Numerical simulation results illustrate that the designed controller can realize anti-synchronization...
According to the great significance of 3D game technology, this paper will do detailed research on main technologies of 3D. Firstly, this paper puts forward to design concept, designs the main frame of 3D game. Secondly, through researching collision detection technologies, the improved collision detection method is proposed based on Aligned Axis Bounding Box according to some disadvantages of collision...
In view of the diversity of factors affecting benefits on fixed assets investment, this article firstly establishes a set of index system reflecting benefits on fixed assets investment; then sets up gray related degree model in accordance with the fact that evaluation information possesses gray characteristics; lastly the model is used to evaluate the benefits on fixed assets investment of the 31...
This paper analyzes the difficulties in the transmission of streaming media, makes research on the packet scheduling on the streaming media server. A Markov model is proposed under the effect of the complex dependency among the streaming media packets and the parameters of the transmission channel. On the basis of the Markov model, a policy is made on the queuing of the streaming media packets in...
