Yii2 redirecting the controller to the home screen

I have a redirection in my yii2 controller footer which goes in at this way.

return $this->redirect(['inventory']);

It is redirecting me to.

http://localhost/['folder']/frontend/web/inventory/inventory

But I want redirection to this.

http://localhost/['folder']/frontend/web/inventory

How can I do that?

This code worked.

return $this->redirect(['../web/inventory']);
