I'm having a problem when trying to solve the algorithm present in the image. I tried to solve by many ways, but results were not satisfactory... The latest try is described in the code, but the following error arises:
KanoModel_02nls.c: In function 'initializeStaticNLSData17':
KanoModel_02nls.c:146: error: 'INTEGER_ATTRIBUTE' has no member named 'nominal'
KanoModel_02nls.c:150: error: 'INTEGER_ATTRIBUTE' has no member named 'nominal'
\MinGW\bin\mingw32-make: *** [KanoModel_02nls.o] Error 1
\MinGW\bin\mingw32-make: *** Waiting for unfinished jobs....
Compilation process failed. Exited with code 2.
Could someone help me solve this problem?
Code:
model KanoModel "Kano stiction model"
Real S = 0.1, J = 0.02;
Real y, u;
Real du(start = 0, fixed = true), us(start=0.5), du_old(start=0);
Integer stp(start = 0, fixed=true), d(start = 1, fixed = true);
algorithm
u := 0.3 * sin(5 * time) + 0.5;
du := u - pre(u);
du_old := pre(du);
// Check if valve stops or changes direction
if (du * du_old) <= 0 and pre(stp) == 0 then
us := pre(u);
stp := 1;
else
us := pre(us);
stp := pre(stp);
end if;
// Assign the valve position
if stp == 0 then
d := pre(d);
y := u - pre(d) * (S - J) / 2;
elseif (-pre(d) * (u - us)) > S then
stp := 0;
d := -pre(d);
y := u - pre(d) * (S - J) / 2;
elseif pre(d) * (u - pre(us)) > J then
stp := 0;
y := u - pre(d) * (S - J) / 2;
else
y := pre(y);
end if;
end KanoModel;
