说明：  基于神经网络的PID控制不是用神经网络来整定PID的参数，而是用神经网络直接作为控制器，通过训练神经网络的权系数间接地调整PID参数。(based on neural network PID control is not using neural networks to PID parameters, Rather, as a neural network controller directly, through the training of the neural network weights indirectly PID parameters to adjust.)

Power system stabilizers (PSS) are now routinely used in the industry to damp out power system oscillations. In this paper, real-coded genetic algorithm (RCGA) optimization technique is applied to design robust power system stabilizer for both singlemachine infinite-bus (SMIB) and multi-machine power system. The design problem of the proposed controller is formulated as an optimization problem and RCGA is employed to search for optimal controller parameters. By minimizing the time-domain based objective function, in which the deviation in the oscillatory rotor speed of the generator is involved stability performance of the system is improved. The non-linear simulation results are presented under wide range of operating conditions disturbances at different locations as well as for various fault clearing sequences to show the effectiveness and robustness of the proposed controller and their ability to provide efficient damping of low frequency oscillations.

非局部均值滤波 图像中的像素点之间不是孤立存在的，某一点的像素与别处的像素点一定存在某种关联，可以概括为灰度相关性和几何结构相似性。这是均值滤波考虑的地方，但是我们还发现，相似像素并不局限于某个局部区域，如图像中的长边缘，结构纹理等，都是相似的。自然图像中含有丰富的重复冗余信息，所以可以采用能够描述图像结构特征的图像块在整个图像上寻求相似块
