Hi

RMAN is smart enough to figure which controlfile it needs for the restore

run{
set until time "to_date('08/28/07 15:00:00' , 'mm/dd/yy hh24:mi:ss')";
restore controlfile to /tmp/control01.ctl;
restore controlfile from /tmp/control01.ctl ;
alter database mount;
restore database;
recover database;
alter database open resetlogs
}

Try something like this
