what is that problem? "Optimization running. Error running optimization. Undefined function 'power' for input arguments of type 'timeseries'"

how can I solve this problem

Optimization running. Error running optimization. Undefined function 'power' for input arguments of type 'timeseries'

I am using matlab R2016a, using genetic algorithm to get the minimum values for PID controller in a switched reluctance motor. please anyone can help tell me how to solve this problem? thanks

Consider for example,

a = timeseries(1:10);
a .^ 2

then that would generate that error, because you are trying to square the timeseries object.

Possibly you want to square the data in the object:

a.Data .^ 2

thanks for your fast feedback, for your info this is my code.

function f = kh (m)
global x1 x2  x3
x1 = m(1);
x2 = m(2);
x3 = m(3);
sim ('genetic_algo')
f = trapz (tout,(spo));
end

is it right or needs a modifications

[Walter Roberson]

What is tout? What is spo? Are those created by "To Workspace" blocks in your simulation ?
