A good place to start might be the web site of the manufacturer of the pressure cooker you have.
Once you get used to them you can pretty much adjust any pressure cooker recipe to the one you have but it is a good idea to get used to the one you have first.
Some pressure cookers have weights that need to be adjusted for various recipes others do not. The weight for the pressure may make a difference in cook time.
