Setting access rule in Yii for action with the same name from different controller?

I searched over the internet and I found nothing. I centralized all of the access rule from all controller in the main Controller.php from components. This is my code:

public function accessRules() {

        $controllers = array(' '); $actions = array('index');
        if (Yii::app()->user->getState("isAdmin") == true){ 
            array_push($controllers, 'controllerName','ModuleName/ControllerName');
            array_push($actions, 'create');
        }
        if (Yii::app()->user->getState('isNormalUser') == true){
            array_push($controllers, 'controllerName2');
        }
        if (Yii::app()->user->getState("isAdmin") == false && Yii::app()->user->getState("isNormalUser") == false){
            return array(
                array('deny', // deny all users
                    'users' => array('*'),
                ),
            );
        }else{ 
            $controllers = array_unique($controllers); //remove duplicates
            $actions = array_unique($actions);//remove duplicates
            return array(
                array('allow',
                    'controllers'=> $controllers,
                    'actions'    => $actions,
                ),
                array('deny', // deny all users
                    'users' => array('*'),
                ),
            );
        }
    }

My problem is: In my module if I have a controller(C1) with a function named f1 and another controller (C2) with the same function name f1 and i want to give access only to C1 with f1? How can I do that? I observed that i can make the difference between modules with the same controller name giving the format

ModuleName/ModuleController Is it smth similar to actions ? Thx
