how should i implement equation in simulink ?

hello ,

how should i implement this in simulink ?

i have phi_dot and w_dot equation that i can use integrator but i have third equation that is a feedback equation and i am not getting how to implement summation and cos (phi)

[Azzi Abdelmalek]

cos (fi) must depend on i.

You can use a N sin wave block from simulink/sources ans sum block from simulink/Maths with N inputs

[Aniket]

this is block diagram and m(t) = 1/N* summation [cos (fi)] in the figure outside summation is summing outputs from N oscillators
