STARTUP MOUNT RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;Apply recovery until all of your archived redo logs have been applied. Then reply CANCEL.
ALTER DATABASE OPEN RESETLOGS;If you do not have a binary backup of your control file, you can create the control file from scratch with the CREATE CONTROLFILE command.

This is why a good backup of your control file is essential. It is easy to make mistakes in the step above. But you can still get the database open. For more information on the CREATE CONTROLFILE command, refer to the Oracle documentation.
Once you have the database open, ensure you have a good backup so that you do not have to repeat this recovery operation in the future.
