It looks as though your intial conditions are 0 for both integrators.
Are you supposed to simulate the system in steady-state? One of your initial values are probably incorrect. Are you given any additional information in your assignment?
(I haven't tried it out, but try setting the intial current to 0.0603). It is almost 90 degrees out of phase with the voltage
current = V/(R+1i*2*pi*f-1i/(2*pi*f*C)); % In steady state (as phasor).
