Amplitude limiting and deblocking filtering of botu PLC signal processing series

For limiting filtering, please refer to the following article ：

PLC Limiting filtering of signal processing ( Siemens MITSUBISHI FB)_RXXW_Dor The blog of -CSDN Blog Limiting filtering is an effective method to eliminate random interference , Compare 2 Adjacent moments k and k-1 Sample value of S(k) and S(k-1), Estimate and determine the maximum allowable deviation of two samples according to the normal value . If 2 The sub sampling value exceeds the maximum allowable error , It is believed that random interference has occurred , And consider the last sampling value S(k) For illegal value , The output signal does not update . For the small fluctuation suppressor, please refer to another blog post ：PLC Jitter suppressor of signal processing series ( Mitsubishi Siemens FB)_RXXW_Dor The blog of -CSDN Blog https://blog.csdn.net/m0_46143730/article/details/125107808?csdn_shttps://blog.csdn.net/m0_46143730/article/details/125111472 advantage ： Inherited “ Limiting filtering ”+“ Dithering filtering method ” Advantages of two kinds of filtering ; Improved “ Dithering filtering method ” Some of the flaws in , Avoid introducing interference values into the system . shortcoming ： It is not suitable for fast changing parameters .

Input parameters can be designed in the filter function block uiSampleCycle Is the sampling period , if uiSampleCycle=1 When, it means that the sampling operation is carried out in each cycle ; if uiSampleCycle&#
