Simultaneous computation of model order and parameter estimation for system identification based on gravitational search algorithm

System identification is a technique used to obtain a mathematical model of a system by performing analysis of input-output characteristic of the system. Most significant steps of system identification process are generally summarized into four main stages. The initial stage is collection of experim...
