the figure bellow represent Shunt APF control template using either MNN or ADALINE structures.
What is Unit template generation in the schematic bellow
I dont understand whats it and whats its role in the control scheme
the reference is : Application of Artificial Neural Networks for Shunt APF Control

Unit template generation:
u =[ua ub uc]=[ Sin(w0t) Sin(w0t-(2*pi/3)) Sin(w0t+(2*pi/3)) ]
(see the text highlighted in the figure attached, it shows an indirect statement that the Sin(w0t) is considered to be in phase with a - phase voltage) Pg. 1768 of same reference
unit templates [ua ub uc] are the sinusoidal shaping signals with unity amplitude. iloss, ||i1,active|| are the loss component and the amplitude of fundamental load currents. from these, the reference source currents are generated as:
is,ref = [ isa,ref isb,ref isc,ref ] = (iloss+||i1,active||) X [ua ub uc]
Anil Kumar Bonala thank you very much. you got the exact answer. .
Anil Kumar Bonala can you please explain how the PI controller gains calculated in the reference. because the ref just put Kp=0.1314 and ki=0.07. and he did not mention how to calculate them
Hello Tamer abdedjebbar
Try to follow the design procedure given in " Proportional–integral/proportional– integral derivative tuning procedure of a single-phase shunt active power filter using Bode diagram" IET power electronics... to obtain the gains Kp, Ki
