摘要
在分析开关磁阻发电机(Switched Reluctance Generator,简称SRG)数学模型的基础上,借助于Matlab/Simulink建立了功率变换器、电流滞环控制器、转子位置角度转换等模块。运用Matlab把电机的电感特性函数转化为二维矩阵,通过Simulink中的非线性插值模块构建了SRG的绕组模块。将这些模块有机结合起来,搭建了SRG系统的非线性仿真模型,并以此模型对12/8结构样机进行了仿真。利用以TMS320LF2407A型DSP芯片为控制核心的数字控制器搭建了SRG系统实验平台,实验结果与仿真结果基本一致,验证了该非线性模型的正确性。
Based on the mathematical model of the switched reluctance generator （SRG）,the power converter block,the rotor angle-calculating block,the hysterics current controller block, etc. are modeled under Maflab/Simulink environment. On the basis of transform of the motor inductance versus current and rotor position,the SRG windings block is modeled by use of the nonlinear interpolation module of Simulink.Combining of these blocks,the nonlinear model of SRG is established.A 12/8 structure SRG control system based on TMS320LF2407A is designed and simulated.The effectiveness of the nonlinear simulation model is demonstrated by the simulation and experimental results.
