Estimate Parameters for System of ODEs using a Genetic Algorithm or a multiobjective generic optimization

Hey there!

I am Takha Abdelghani ,I want to use a Genetic Algorithm or a multiobjective generic optimization for optimization based parametres of the FO nonlinear dynamical system , I would be very happy to assist me with my research .

%===My model===============================

xi = cos(ti);

yi = sin(ti);

ta = atan2(x(2),x(1));

dti = rem(ta - ti, 2*pi);

%%%My variables

ai = [1.2 -5 30 -7.5 0.75];

bi = [0.25 0.1 0.1 0.1 0.4];

ti = [-1.0472 -0.2618 0 0.2618 1.5708];

%%%My model

dx1dt = a0*x(1) - pi*x(2);

dx2dt = a0*x(2) + pi*x(1);

dx3dt = - sum(ai.*dti.*exp(-0.5*(dti./bi).^2))- 1.0*x(3) ;
