摘要
结合现代控制理论知识,提出了电励磁同步电机的全阶磁链观测模型。根据电励磁同步电机电压及磁链方程推导出其状态方程,并判断了状态方程的可控性及可观测性。根据状态方程设计了电励磁同步电机的全阶磁链观测器,推导出其系统矩阵,并确定了反馈矩阵。在MATLAB/Simulink平台上对整个系统做仿真研究,并对仿真结果进行分析,磁链在全速范围内能准确观测。
Taking into account these issues,full-order flux observer model of electrically excited synchronous motor based on knowledge of modern control theory was presented.Its state equation was derived based on its voltage and flux equations,its controllability and observability were determined too.According to state equation of the electrically excited synchronous motor design full-order flux observer,the system matrix was derived,and the feedback matrix was determined.Finally,simulation was done for whole system on MATLAB / Simulink platform,and the simulation results were analyzed.The flux could be observed accurately in the speed range.
