Hi there!

I want to  plot phase portraits of this fractional system in maple please help me.


                          (alpha_1)
                         D              T = q-a*T+r*T(1-(T+I)/T_max)-k*V*T,



                          (alpha_2)
                         D              I = k*V*T-β*I,



                          (alpha_3)
                         D              V = N*β*I-γ*V,


with the initial conditions: T (0) = r1, I(0) = r2 and V(0) = r3.

we set q = 0.1, a= 0.02, β = 0.3,
r = 3, γ = 2.4, k = 0.0027, N = 10, T_max = 1500.
