A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied  which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion  and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio  high precision  compact structure  high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera  the location relationship between the displacement of focusing structure and the focal plane movement is derived  and the system error is analyzed  its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70  repeated positional accuracy is 2m  which meet the requirements for use. 2010 SPIE.

In view of domestic traffic  the traffic flow is increasing rapidly recent years  whereas the traffic control is deficient. This paper presents a design of intelligent traffic control system based on DSP and Nios II. Using Dual-CPU  Intelligent Traffic Control System combined with logic control in FPGA implements kinds of functions  which include crossphase adjustment  exchanging and establishing related information  live human-computer interaction and remote control etc. The system works mostly at the mode of timing and multiple phases according to the user demands dynamically  thus it breaks through the bottleneck of traditional traffic signal controller  and can accomplish the control in complicated and diversified traffic. This paper gives the realization of hardware system as well as the software system. The experiment results show that the Intelligent Traffic Control System can completely meet the requirements of modern traffic control. 2009 IEEE.

Optimizing the control mode of optical payload could improve the payload's work efficiency. When the mathematic model of payload's control mode was established  optimization problems could be boiled down to seek the maximal value of the function with many variables. This paper put forward a calculational method to base the mathematic model  the calculational method was multi-population genetic algorithm (MPGA). After the 0-1 variables and real multidimensional ones had been coded separately  the algorithm established the populations independently  made the multidimensional variables as the centrosome and combined 0-1 ones to work out the maximal value of the function which was established to describe the control mode of the optical payload. Moreover  the emulational experiment had been done with the material arithmetic operators. The result indicates that the method using MPGA can hurdle the disadvantage of traditional ones which calculate slowly and get into local best value trap easily . It has the characters that not only fits large scale area scout  but also gets the best value in full scale rapidly  so this algorithm can better satisfy the technology demand for the intelligent control of optical payload. 2009 IEEE.
