If you're using Phalcon\Mvc\Micro, I'm sorry to tell you that it's hard to get the right answer.I had a similar problem before, so I analyzed $event and $app using PHP's reflection mechanism and came up with the following answer:

<?php

    $eventsManager = new \Phalcon\Events\Manager();
    $eventsManager->attach(
        'micro:beforeExecuteRoute',
        function (\Phalcon\Events\Event $event, $app) {
            $controllerName = $event->getSource()->getActiveHandler()[0]->getDefinition();
            $actionName = $event->getSource()->getActiveHandler()[1];
        }
    );

    $app = new \Phalcon\Mvc\Micro($di);
    $app->setEventsManager($eventsManager);

Exciting controllers? It all depends on what excited them…

But srsly, you can only get the instance of the active controller from the dispatcher, that can be accessed like this:

$controller = $di->getShared('dispatcher')->getActiveController();

If you are using event handler with event manager, than like this:

$eventManager->attach("dispatch:beforeExecuteRoute", function (Event $event, Dispatcher $dispatcher) {
    $controller = $dispatcher->getActiveController();
});

If you actually meant existing controllers as plural, then you'd need to add some sort of tracking for controller instantiation. You can't do this via __construct in your controller classes, because for some reason some genius marked __construct as final. The other option would be to add that tracking in your beforeExecuteRoute and beforeNotFoundAction event, dig the code in the repository for details:

// Exciting controllers get stored whenever the dispatcher reports if the action was not found
// or when it's ready to dispatch. Note, if a controller gets created outside the dispatcher
// it will not be tracked, though in real life that should never happen.

$controller = [];

$eventManager->attach("dispatch:beforeNotFoundAction", function (Event $event, Dispatcher $dispatcher) {
    $controllers[] = $dispatcher->getActiveController();
});

$eventManager->attach("dispatch:beforeExecuteRoute", function (Event $event, Dispatcher $dispatcher) {
    $controllers[] = $dispatcher->getActiveController();
});
