Abstract

Digital Electro Hydraulic (DEH) control System, a key element including the nonlinear aspects, is an important control component of the steam turbine control system. The changes in parameters of DEH affect greatly on dynamic characteristics and quality of electricity produced by steam turbine. This paper study the parameter identification on DEH, propose a multi-particle swarm optimization method (MPSO) to increase the accuracy of DEH parameter identification. Then a test platform was designed for DEH with MPSO model. Performance test gives out detail performance parameters of hydraulic actuator which verify the veracity of DEH parameter identification based on MPSO.
