摘　　要：研究了现场可编程门阵列(field-programmable gate array,FPGA)Nios II多核实现方法,讨论了电池RC模型和加权PID算法。通过运用多核控制算法和FPGA实现提高了实时处理速度。根据电池的外特性搭建了锂离子电池RC模型,依据电池模型的系统特性设计了加权PID算法,用Nios II多核对加权PID控制器进行实现,进行了基于FPGA和dSPACE实时仿真系统的电池充电实时仿真实验。实验结果表明,基于Nios II多核的加权PID控制器可以很好地控制电池在设定条件下快速充电。Nios II multi-core implementation based on FPGA is studied. Modelling RC battery model and designing weighted PID control algorithm problems are also discussed. The use of multi-core control algorithm and implementation with FPGA increase real-time processing speed. Firstly lithium ion battery＇s RC model is built based on battery＇s external characteristics, secondly according to battery model＇s system property, weighted PID control algorithm is designed, thirdly weighted PID control algo- rithm is realized by Nios II multi-core program, finally, battery charging rapid prototyping experiment, which is based on FPGA and dSPACE real-time simulation system, is performed. The experimental results show that the designed weighted PID control- ler can well control the process of battery＇s fast charging under set conditions.
