The value on u1max and u1min are supposed to be the limitations for the aircraft components and they are supposed to be connected with u1. i want to get the answer for them same as 91*1 double just as for u1.
u1min = -25*pi/180;
u1max = 25*pi/180;
u2min = -25*pi/180;
u2max = 10*pi/180;
u3min = -30*pi/180;
u3max = 30*pi/180;
u4min = 0.5*pi/180;
u4max = 10*pi/180;
u5min = 0.5*pi/180;
u5max = 10*pi/180;
if(u1)>u1max
u1 = u1max;
elseif(u1)<u1min
u1 = u1min;
end
if(u2>u2max)
u2 = u2max;
elseif(u2<u2min)
u2 = u2min;
end
So this is the coding i generated and i also put u1 = u1min and u1max. but the program is not reconizing those calculated u1min and max as the limits. i have seen someone use this code, it wored for them but its not working for me. When i try to plot the graph i only see u1 values as it is not getting connected to u1min and u1max. Is there any way i could connect those limits and get the answer in double.

This is the u1 data result i am getting. On this graph i want a straight line showing u1 data and also u1 min and max together.

Ran in:
i am not so clear about your expectation. my guess
A=load('u1.mat');
u1=A.u1;
u1min = -25*pi/180;
u1max = 25*pi/180;
u2min = -25*pi/180;
u2max = 10*pi/180;
u3min = -30*pi/180;
u3max = 30*pi/180;
u4min = 0.5*pi/180;
u4max = 10*pi/180;
u5min = 0.5*pi/180;
u5max = 10*pi/180;
for n=1:length(u1)
if u1(n)>=u1max
u1(n) = u1max;
elseif u1(n) <= u1min
u1(n) = u1min;
end
end
u1=[u1min;u1]; % if you want u1min. if don't then omit this line
plot(u1)
