说明：  四旋翼无人机是一种具有六个自由度和四个输入的欠驱动强耦合、外型新颖结构简单的飞行器。由于其具有制造成本地、重量轻、体积小、操作简单、使用方便、隐身性好、对作战环境要求低的特点，使其能准确、高效的执行各种军事或民用任务，因此四旋翼无人机具有一定的军事和民用价值。本课题针对四旋翼无人机的特点和飞行原理，对其动力学分析以及运动控制的研究，利用牛顿—欧拉方程，建立了四旋翼无人机的动力学模型,并针对该模型设计了PID四通道控制系统,且在Matlab/Simulink仿真平台上,利用PID控制系统对四旋翼无人机进行仿真，完成了对四旋翼无人机运动控制和与地面运动物体的交会，仿真结果表明：仅仅通过改变四只旋翼的转速来改变升力，进而改变四旋翼无人机的姿态控制和位置控制，从而实现了四旋翼无人机的运动控制以及与地面运动物体的交会。(Height Control of Four-Rotor Aircraft)

说明：  用QT编写的传感器测试系统界面，可用于二次开发(Sensor test system interface written with QT can be used for secondary development)

Michael喜欢滑雪百这并不奇怪， 因为滑雪的确很刺激。可是为了获得速度，滑的区域必须向 下倾斜，而且当你滑到坡底，你不得不再次走上坡或者等待升降机来载你。Michael想知道在一 个区域中最长的滑坡。区域由一个二维数组给出。数组的每个数字代表点的高度。 (Michael likes to ski hundred This is not surprising, because the skiing is very stimulating indeed. However, in order to obtain speed, Waterloo regional must be downward-sloping, and when you slide into the base, you have to embark once again on the slope or to set you waiting for lifts. Michael would like to know the longest in a landslide area. Region is given by a two-dimensional array. Each figure represents an array of high points.)

说明：  利用最小二乘法对曲线进行二次拟合，简单的例子(Quadratic fitting of curve by least square method, simple example)

说明：  采用D-H法建立了多自由度机械臂末端执行器相对于基础坐标系的位置与姿态，即多自由度机械臂的正运动学模型。其次对多自由度机械臂的逆运动学模型进行了分析。最后通过采用Langrange法对多自由度机械臂的动力学进行了建模，并对多自由度机械臂的动力学模型及其特点进行了分析。 针对多自由度机械臂数学模型的不确定性问题，提出一种基于RBF神经网络的机械臂自适应控制方法。(The position and attitude of the end effector of the multi DOF Manipulator relative to the basic coordinate system is established by using the D-H method, that is, the forward kinematics model of the multi DOF Manipulator. Secondly, the inverse kinematics model of multi DOF Manipulator is analyzed. In the end, the dynamics model of the multi degree of freedom manipulator is established by using the Langrange method, and the dynamics model and characteristics of the multi degree of freedom manipulator are analyzed. Aiming at the uncertainty of the mathematical model of the multi degree of freedom manipulator, an adaptive control method based on RBF neural network is proposed.)
