Based on the gray square weighted centroid localization algorithm  the paper presents bicubic interpolation gray square weighted centroid localization algorithm  increases the number of effective pixels around the optical characteristic point imaging center  and reduces noise error via the gray square weighted  improves the imaging center location accuracy of optical characteristic point  realizes the accurate location of the optical characteristic points. Results indicate application of the proposed algorithm to location  the standard tolerance along the direction of x is 0.0022 Pixel  the standard tolerance along the direction of y is 0.0023 Pixel  compared with the others  the standard tolerance is minimum and discrete to a lesser degree distancing ideal image point  that is  the proposed algorithm has higher location accuracy. The maximum tolerance along the direction of x is 0.008 Pixel  the one along the direction of y is 0.007 Pixel  compared with the other two algorithms  the maximum tolerance is minimum.Results indicate that the stability of the proposed algorithm is better.

By designing the double loop configuration  the autonomous trajectory tracking is realized. The model uncertainty  external disturbance and the senor noise are also taken into consideration. Then the H controller is put forward in the inner loop. An optimal stability augmentation control (SAC) method is used to stabilize the horizon position and keep it away from oscillation. By calculating the nonlinear decouple map  control quantity is converted to the speeds of the four rotors. At last some simulation results and the prototype implementation prove that the control method is effective.   Control method research on wide flight envelope aerocraft (EI CONFERENCE) 会议论文  OAI收割 2nd Annual Conference on Electrical and Control Engineering, ICECE 2011, September 16, 2011 - September 18, 2011, Yichang, China 作者:  Duan Z. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 The flying qualities of aerocraft was directly effected by the autopilot  for the wide flight envelope aerocraft  on the basic of analyzing the typical trajectory  the three loop autopilots of roll stability  pitch and yaw were designed  using single-mode Transient suppression method  the overload due to control surface transition deflection was avoided when control parameters changing  the verification was done by non-linear simulation. The result showed that: Under the action of the disturbance torque  the maximum roll was less than 5  the range of the aerocraft was from 13.5km to 22.4km  the max height was about 5100m  the max deviation of lateral was about 42m  the maximum elevator deflection was less than 6.5 the control law was applicable within the effective range. An autopilot design method of wide flight envelope aerocraft was provided. 2011 IEEE.   Structural and electronic properties of silver-doped gold clusters Au(n)Ag(v) (2 <= n <= 10; v=0,+/- 1): comparison with pure gold clusters 期刊论文  OAI收割 Molecular Physics, 2011, 卷号: 109, 期号: 16, 页码: 2057-2068 P.

C. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 In this paper  we present a new thermo therapy of tumor control algorithm  in which a self-regulation factor is adopted to realize real-time temperature control with high-precision fuzzy controller. This method can not only realize the real-time control with ignoring influence of impedance parameters  but also enhance the stability and dynamic characteristics of the control system  and the performance of the radio-frequency thermo therapeutic equipment is enhanced. We have demonstrated this strategy is feasible and effective based on the experiment researches of liver tumor thermo therapy 2007 IEEE.
