You cannot use a current controlfile and current datafiles to do incomplete recovery. If you are missing your online logs then your recovery is going to be incomplete. Your option is to verify all files have the same checkpoint_change# before begining recovery.
SQL> select file#, checkpoint_change# from v$datafile;
If they are all the same then use recover until cancel.
SQL> recover until cancel using backup controlfile;
cancel
SQL> alter database open resetlogs;
Make sure the directories for the redologs exits before resetlogs and they will be generated by the database automatically at open.
