Is it possible to find Pspice model for LD7552 and JT3028?

I would like to add the JT3028 and LD7552 components in Orcad Cadence to simulate PWM source circuits . Even, if possible, a website or program that teaches you how to model these components.

The LD7552 and JT3028 models don't appear to be in the Cadence PSpice model library.  However, the ON semi MC33364 SMPS controller is in the PSpice on_pwm.lib and has a detailed spec sheet on the ON semi site (https://www.onsemi.com/pub/Collateral/MC33364-D.PDF).  You can study the model and compare it to the performance specification and application information from the ON semi part.  That may give you insite to developing models for the other two controllers you're interested  in.
