The modeling and attitude stabilization control problems of a four-rotor vertical takeoff and landing unmanned air vehicle (UAV)
known as the quadrotor are investigated.The quadrotor’s attitude is represented by the unit quaternion rather than Euler angles to
avoid singularity problem. Taking dynamical behavior of motors into consideration and ignoring aerodynamic effect, a nonlinear
controller is developed to stabilize the attitude.The control design is accomplished by using backstepping control technique.The
proposed control law is based on the compensation for the Coriolis and gyroscope torques. Applying Lyapunov stability analysis
proves that the closed-loop attitude system is asymptotic stable. Moreover, the controller can guarantee that all the states of the
system are uniformly ultimately bounded in the presence of external disturbance torque.The effectiveness of the proposed control
approach is analytically authenticated and also validated via simulation study.

OMP
OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing

FastICA134
在诸多ICA算法中，固定点算法 (也称FastlCA)以其收敛速度快、分离效果好被广泛应用于信号处理领域。该算法能很好地从观测信号中估计出相互统计独立的、被未知因素混合的原始信号。(In many ICA algorithms, fixed-point algorithm (also known as FastlCA) for its fast convergence and good separation effect is widely used signal processing. The algorithm can estimate from the observed signals statistically independent each other, unknown factors are a mixture of the original signal.)
