49377 首先建立含参数不确定与外界干扰的高超声速飞行器模型; First established with parameter uncertainty and external disturbance of hypersonic flight vehicle model;
49378 而后基于动态逆思想，将动力学模型进行线性化，并将由参数不确定与外界干扰对系统造成的总效果看作系统总干扰，从而引入线性扩张状态观测器实现对系统状态及总干扰的估计; And then based on dynamic inversion, the linear dynamics model, and will be caused by parameter uncertainty and external disturbance on the system as the total effect of the system total interference, thus introducing linear extended state observer to realize the estimate of the state of the system and total interference;
49379 最后考虑总干扰作用，提出具有鲁棒性能的动态逆控制律与滑模控制律。 Finally, considering the total disruption has robust performance dynamic inversion control law with the sliding mode control law.
49380 通过与传统控制律进行对比仿真，结果表明所设计的两种鲁棒控制器只需在原有方法基础上进行简单改进，即可较大程度提高对系统参数不确定与外界干扰的鲁棒性，具有良好的跟踪性能。 Compared with traditional control law for the simulation, the result shows that the two kinds of robust controller designed just simple improvements on the basis of the original method can greatly improve the system robustness of parameter uncertainty and external disturbance, has the good tracking performance.
49381 Harris算子是经典的角点检测算法，但却存在检测性能依赖高斯窗窗长和阈值的不足，本文对此做出改进。 Harris operator corner detection algorithm is a classic, but it is gaussian window and threshold detection performance depends on, this article to make improvements.
49382 先设定较低阈值，检测出图像中的疑似角点。 To set a lower threshold, to detect the Angle of suspected points in the image.
49383 再构造一个新的圆环模板，通过内外两个圆环上的像素点评估中心像素邻域灰度变化， To construct a new circle template, by inside and outside the two rings on the pixel assessment center pixel neighborhood grayscale change,
49384 用构建的新模板遍历每一个疑似角点，滤除虚假角点，得到最终检测结果。 with building new template traverse every suspected angular point, filter out the false corners, get the final test results.
49385 本文算法计算内外两个圆环上像素的灰度变化，充分考虑了角点在局部区域灰度变化明显的特征， Algorithm to calculate the internal and external two rings on the pixel gray level change, give full consideration to the corner in the local gray level change is obvious characteristics,
49386 不涉及微分运算，所以具有较好的鲁棒性。 does not involve the use of differential operators, so it has better robustness.
