c=1;
for i=0:10
c= 0.2+c;
u=fprintf('SOUR:VOLT %dV, (@2)',c);
fprintf(obj, 'u ');
end
also the in second try i use concatenation of string like given below
for i=1:4

You have
u=fprintf('SOUR:VOLT %dV, (@2)',c);
you are trying to use an integer format, %d, for a non-integer value, which is changing by 0.1 at a time. You should use
u=fprintf('SOUR:VOLT %.1fV, (@2)',c);
