Nonlinearity of underwater vehicles(UVs) and complexity of working environments make the precise control of AUVs difficult for some of the intelligent operations. Based on the analysis of fuzzy control and combined with the form of PID control, S plane control is a simple and effective method, but parameters must be manually set for its controller. Improved simulated annealing algorithm is introduced to S plane control method to optimize the controller's parameters automatically. The feasibility and advantages of the algorithm has been demonstrated by simulation results.

Supersonic target cruise missile flying at zero is a dynamic practical simulator, which simulates the terminal flight character of anti-ship cruise missile. In order to simulator the flight height of anti-ship cruise missile, the target cruise missile must fly low. The transitional ballistic trajectory of supersonic target cruise missile from high to low is important for flying control. In this study, supersonic target cruise missile is investigated and the controllable particle math model is constituted in order to obtain the optimizing transitional ballistic trajectory. Principle of the minimum of optimum control is used to optimize the transitional ballistic trajectory. The results have an important theoretical value for fight control on transitional ballistic trajectory.

In this paper, the license location is adopted by using mathematical morphology and edge detection. Using the erosion operation with the horizontal structure element and the subtraction operation, we cope with the gray image turned into by the inputted color license image in order to obtained the gray image with the prominent license plate characters. Then detect the edge of the gray image by using the sobel operator. Eliminate the noise in the obtained binary image by using the erosion operation with horizontal structure element and then by using the close operation of the mathematical morphology. Some connecting areas are formed. Take two thresholds filter the connecting areas so that the connecting area with the license plate is confirmed. Achieve the accurate location of the license plate by the area preparations and the scanning row and column. The algorithm is carried with 76 color license plate pictures. The results show that the positioning accuracy rate of this algorithm comes up to 96%, and it can meet certain real-time requirements.
