Firstly, the continuous state branching processes arose from limit processes of rescaled Bienaymé-Galton-Watson (BGW) processes. A controlled branching process (CBP) is a modification of the standard BGW process in which the number of progenitors in each generation is determined by a random mechanism. It is the aim of this talk to research the limit of the rescaled controlled branching processes. In particular, we consider a CBP starting from a random number of initial individuals and provide a Feller diffusion approximation for rescaled critical CBPs making use of limit theorems for random step processes.
