Probably a typo at the last line of this code below. Should be 'sys', not 'sym'. Also need to add a line 'end' to finish this function. Do the same for other functions too.
function sys=mdlOutputs(t,x,u,pa)
%X1 hatd x2 wm x3 wmref
r7=pa.r7;
Pn = pa.Pn;
Phi = pa.Phi;
J = pa.J;
B = pa.B;
T=pa.T;
Ts=pa.Ts;
if t<=Ts
n =T/(T-t);
n1=T - t;% n/diff(n)
else
n=T*(1+a*(T-Ts))/a/(T-Ts)/(T-Ts)-T/a/(T-Ts)/(T-Ts)*exp(-a*(t-Ts));
n1= - (exp((-a*(Ts - t)))*(exp(a*(Ts - t)) - T*a + Ts*a - 1))/a;
end
hatd=u(1);
hatwm=u(2);
