I'm afraid that I've not seen any IDE that knows how to recognize the docblock template syntax of /*#@+/.
As for $this->MyModel, you could try using the @property tag on that class where you are using $this->MyModel.
Although some IDEs can reportedly recognize that @var syntax to set a datatype on a local variable:
/** @var \MyModel $model */
$model = $this->MyModel;
I don't think it would work with a class property like that.
