Put a back slash before Core OR use Core in the top of the controller
$html = \Core::make('helper/html');

Chrome browser REALLY likes to cache CSS files. Make sure you're cache is really clear or try another browser that's never seen that site before to see if the CSS is kicking in.

'path/to/my.css' means you have to use your real path to the css file, e.g. application/theme/starter_theme/YOUR_CSS_FILE.css

Try this in your controller:
public function registerViewAssets($outputContent = '')
{
    $html = $this->app->make('helper/html');
    $this->addHeaderItem($html->css("application/theme/starter_theme/YOUR_CSS_FILE.css
"));
}

Then clear site cache in Dashboard, reload the page Ctrl-F5 and check if your css loaded in the page source.

Thanks a lot linuxoid.
I also tried your code too.But doesn't work.
I was wrong.The php file I want to design is view page.I call controller php file from form in view.
