The scalar control research based on fuzzy PID of BDFM stand-alone power generation system

Abstract

BDFM as an independent power generation have a very wide application, the control strategy is different from its control strategy in paralining to network. In this paper, We use a wound rotor BDFM for example, analysis the principle of BDFM stand-alone power generation, and the unique structure of its control system. As an independent power source to meet the power winding voltage amplitude and frequency, We discuss the theory and the control strategy of the BDFM generation by power winding voltage amplitude and frequency of closed-loop. And also We simulate all kinds of states of the stand-alone power generation. Comom PID control has the shortcoming of large shocks in sudden change process. This paper discuss the Mamdani Fuzzy PID control model which can achieve optimal control of the process through an amendment to the control parameters, With 64kW experimental prototype and the development of scalar control system of the system also confirmed the correctness of this control strategy.
