% i just changed these to suit my example TF

N = [2e-1,1e-1,1e-2];

% you can just move this outside the loop to avoid the conditional

figure

hold on

legendstrings=cell(size(N));

for i = 1:length(N) % make stuff independent of array sizes

Tau1 = N(i);

% idk what your TF is or how tau is used in it

% this is just some garbage i made as an example

H = tf([1 0.1 7.5*(1-Tau1)],[1 0.12 9 0 0]);

bode(H)

% build the legends from the parameters themselves

% instead of using literal strings that might be wrong if N changes

legendstrings{i}=sprintf('Tau1 = %2.2e',Tau1);

end

hold off

legend(legendstrings,'location','northwest') % you can just set the location as needed

grid on
