ISO 2631 Acceleration filter

Hi guys,

I currently want to filter this acceleration curve by using ISO 2631 standard,

It would be a big save of time if you alreadly have the code of this filter,

And I very appreciated it, thanks so much guys

That function does not appear to exist anywhere in MATLAB (R2022b):

which iso22631 -all

'iso22631' not found.

It may be available in the Fille Exchange, however I did not do that search.

.

hello

found this , but as I don't have the ISO standard to double check , use at your own risks

%ISO 2631 standard filter
% Hw = tf([4*pi 2*pi*2*4*pi],[1 2*pi*2/0.63 (2*pi*2)^2]); %weighting filter
Hw_num = [4*pi 2*pi*2*4*pi];
Hw_den = [1 2*pi*2/0.63 (2*pi*2)^2];

% Hu = tf([1 0 0],[1 2*pi*0.4/0.71 (2*pi*0.4)^2]); % 2HP
Hu_num = [1 0 0];
Hu_den = [1 2*pi*0.4/0.71 (2*pi*0.4)^2];

% Ho = tf((2*pi*100)^2,[1 2*pi*100/0.71 (2*pi*100)^2]); % 2LP
Ho_num = [0 0 (2*pi*100)^2];
Ho_den = [1 2*pi*100/0.71 (2*pi*100)^2];

% HC = Hw*Hu*Ho; % transfer fcn of comfort filter (ISO)
[HC_num,HC_den] = series(Hw_num,Hw_den,Hu_num,Hu_den);
[HC_num,HC_den] = series(HC_num,HC_den,Ho_num,Ho_den);

bode(HC_num,HC_den)
