design of boost converter

[dark night]

hi,
i have designed a boost converter circuit with input voltage 12v, and the other elements as shown in attached figure
so, my problem is the output of this circuit is right (as shown), and also i got the result of the inductor voltage, but am sure its wrong.
any body help me

The solid green is parasitic oscillations.

Of course you want to get rid of them. You may have to try a dozen things.

Such as:

Increase/decrease resistances.

Try load with different resistance values.

Put a capacitor across this or that component.

Try a different power supply.

Etc.
