A system of frequency converter based on DeviceNet Fieldbus

Abstract

Network control for a system of frequency converter is designed based on DeviceNet Fieldbus in the paper. Some functions about transducer, such as parameter setting, fault diagnosis and alarm can be realized by network. The problem, that each parameter can not be taken into account synchronously, is solved by adopting adaptive PI control. Experimental results show that the dynamic performance and the steady-state accuracy of the system are improved.
