This paper proposes that the dual-rate system is transformed from a lifted state-space model to the difference equation of transfer function. An improved particle swarm optimization (IPSO) algorithm is presented to estimate the transfer function's parameters. Comparing the simulation results with a recursive least squares (RLS) the algorithms of IPSO(More)
This paper presents a new method of multi-rate system identification based on improved particle swarm optimization (PSO). The paper discusses multi-rate system transformation based on the lifting technique. The coefficients of multi-rate systems with the state-space model are estimated using least square estimation technique and improved PSO techniques,(More)
