Wind turbine model block, cp(lambda, beta) function syntax error

조회 수: 36(최근 30일)
Hello, I am trying to run a wind turbine model block from simscape, and I am getting this error.
The expression: c1*(c2/u[2]-c3*u[3]-c4)*exp(-c5/u[2])+c6*u[1]
in 'Wind turbine model/cp(lambda,beta)/Fcn1'
has a syntax error
This formula is the generic equation to model cp(lmbda,beta), what am I doing wrong? Do I need to define the coefficients or is it a simple syntax error? I have attached pictures of the wind tubine block parameter

Hello Giovanni,
I understand that you are getting syntax error using MATLAB function block in Simulink.
The cause of this error is the use of square brackets [ ] for indexing the input vector. Instead, you can try using the following syntax to solve the issue.
function y = fcn(u)
y = c1*(c2/u(2) c3*u(3) c4)*exp(-c5/u(2)) + c6*u(1);
Hope this resolves your issue.
Thank you.

The error clearly tells you that the math expression has a syntax error, which is a common error when programmer uses some characters incorrectly, or misses some punctuation marks.
In your case, you should use the hyphen-minus (-) an ASCII character, as if it is directly entered from the keyboard.
In short, use (-) instead of (–).
