【Abstract】 According to the development trend of domestic and overseas excitation control system,the excitation control system with fuzzy serf-regulating PID function is studied and designed,which uses Altera CycloneⅡEP2C20F484C7 FPGA as its control chip. The design bases on SOPC technology and adopts FPGA-based NIOSⅡCPU.Muhi-NIOSⅡCPU architecture is tried to use when implementing the design scheme,based on which the hardware design & software implementation for control arithmetic are validated successfully.The experiment results show that the excitation voltage needed by the double NIOSⅡCPU-based excitation control system can be rapidly & stably obtained,and the system has a good application prospect.更多还原
