摘要
根据国内外励磁控制系统发展的趋势,研究与设计了以Altera CycloneⅡEP2C20F484C7 FPGA为核心控制芯片,具有模糊自调节PID的励磁控制系统。设计中以SOPC技术为基础,采用基于FPGA的NIOSⅡ核处理器,在实现设计方案的同时尝试使用了多NIOSⅡ核架构,成功验证了硬件设计和控制算法的软件实现。实验证明,基于双NIOSⅡ核的发电机励磁控制系统能够快速、稳定地达到所需励磁电压,具有很好的推广前景。
According to the development trend of domestic and overseas excitation control system, the excitation control system with fuzzy self-regulating PID function is studied and designed, which uses Altera Cyclone Ⅱ EP2C20F484C7 FPGA as its control chip. The design bases on SOPC technology and adopts FPGA-based NIOS Ⅱ CPU. Multi-NIOS Ⅱ CPU 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 NIOS Ⅱ CPU-based excitation control system can be rapidly ＆ stably obtained, and the system has a good application prospect.
