Adopt mean value wave filtering way to dislodge noise to the image(Adopt mean value wave filtering way to disl odge noise to the image)

利用频域滤波消除周期噪声，即用频域带阻滤波器消除图像中的周期噪声。(By using the frequency domain filtering eliminating cycle noise, use frequency domain band-stop filter to eliminate image noise of the cycle.)

有一个3阶对象，要求使用继电自整定方法对其实施自适应PID控制。 要求： 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (A 3-order object, requires the use of relay self-tuning PID control methods on the implementation of adaptive. Requirements: 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)
