Solve linear system of ODEs with periodic coefficient












0












$begingroup$


I am trying a solve a system of linear ODEs with periodic coefficients.



x'(t)= a11*x(t) + a12*(1 + km*Sin(w*t))*y(t) + b1*Sin(w*t) 
y'(t)= a21*x(t) + a22*(1 + km*Sin(w*t))*y(t) + b2*Sin(w*t)


Here a11, a12, a21, a22, b1, b2, and km are constant.



I have read some articles and found that Floquet theory is more appropriate approach to solve, but I am having difficulty to find the fundamental matrix.



Any suggestion to analytically solve these equations.



Thank You
