As you do not have control file backup, you must recreating this way, especify all your data files control file, database name and parameters to suit your configuration.

create a sql script and add (ORCL is a example instance name):
CREATE CONTROLFILE REUSE DATABASE "ORCL" RESETLOGS ARCHIVELOG
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 14
MAXINSTANCES 1
MAXLOGHISTORY 226
LOGFILE
GROUP 1 'E:\ORACLE\ORADATA\ORCL\REDO01.LOG' SIZE 100M,
GROUP 2 'E:\ORACLE\ORADATA\ORCL\REDO02.LOG' SIZE 100M,
GROUP 3 'E:\ORACLE\ORADATA\ORCL\REDO03.LOG' SIZE 100M
DATAFILE
'E:\ORACLE\ORADATA\ORCL\SYSTEM01.DBF',
'E:\ORACLE\ORADATA\ORCL\UNDOTBS01.DBF',
'E:\ORACLE\ORADATA\ORCL\EXAMPLE01.DBF',
.... <- More datafiles here
CHARACTER SET WE8MSWIN1252 <- change
;

ALTER DATABASE OPEN RESETLOGS;

and rename it to ctl.sql

Then startup the database in nomount mode and run the ctl.sql file as sys as sysdba user
