If you need to access the getConfigData() function from your controller do this:
Mage::getModel(‘<name of the model for this controller>’)->getConfigData(<fieldname>);
For example if you want to call getConfigData() from the Mage_Mymodule_MyworldController controller then:
Mage::getModel(‘Mage_Mymodule_Model_Myworld’)->getConfigData(<fieldname>);
