Buffer cache is implemented using bufferpool right(I mean in the main
memory).how about system cache? Can we control the size of system cache?

Buffer cache is the cache managed by the buffer manager, that caches any
blocks from any relation used in the system. All access to relations go
through the buffer cache, using ReadBuffer/ReleaseBuffer (etc.) calls. It's
implemented in src/backend/storage/buffer/bufmgr.c
