Access params of module

In a model of a module (LocationModule) I can access params like this:

$arrImageSize = Yii::app()->controller->module->arrImageSize;

how can I access the same property from SiteController.php (not in LocationModule)?

Yii::app()->moduleID->params['xxx']

However, this usage should be avoided because it betrays the original intention of using module.

Yes, but sometimes I need to access a module from another module or controller.

If I do so, I'll get an error:

CWebApplication.location is not defined.

Sorry, it should be getModule(moduleID)
