polarcode_scl

本程序实现了matlab自带函数imfillter的功能，是.m文件的形式，参数和imfilter一样可选。程序附有图片，并且在程序最后使用imfilter，便于直接对比观察处理效果。注：本程序是读入RGB图像，转换成灰度图进行处理。(This program implements the function of matlab own function imfillter is. M file in the form of the same parameters and imfilter optional. Procedures with pictures, and last used in the program imfilter, for direct observation of treatment effect contrast. Note: This program is read into the RGB image into grayscale processing.)

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.
