In 9i RMAN you can "configure controlfile autobackup on" - that way RMAN always backs up controlfile as well during any backup. You just have to note that if you configure controlfile autobackup on, then this is remembered in controlfile and during several physical database operations like adding datafile, creating/dropping tablespace, taking tablespace/datafile online a controlfile backup is also created (default location $ORACLE_HOME/dbs or database). If you don't take it into account you could have hundreds of old controlfiles lying around if your environment involves a lot of physical structure changes (transportable tablespaces, read only/read write tablespaces etc).
