Hi,

I designed a boost DCDC converter 11V to 19V @3A load in CCM and a voltage mode type 3 copensator.

I get this step response from simulation. Is it ok or should I redesigned my compensator?
Steady state response is ok, but I am worried about transient response.
Should it be without oscillations?

Yeah your feedback compensation needs some tuning. You have a lot of ringing, but the low frequency gain is also too low. Try increasing your zero frequencies while decreasing your pole frequencies (basically reduce your k factor).
