摘　　要：在分析级联式无刷双馈感应电机的数学模型的基础上 ,以小信号线性化增量模型为手段 ,根据李雅普诺夫稳定判据得出其稳定性的条件 ;而后对级联式无刷双馈感应电机矢量控制系统进行了仿真研究 ;最后分析了控制系统在典型工况下的动、静态品质。实验结果证明了其完全可以达到与直流电机控制系统的性能以及仿真分析的正确性。在国内首次研制成功该类电机矢量控制系统样机。为级联式无刷双馈感应电机进一步广泛应用于风力、水力变速恒频发电等领域 。This paper firstly presents the mathematical model of CBDIM,and studies its stability conditions by means of its small signal linear model and Lyapunov theorem.Then the simulation including CBDIM,cyclo converter,vector control system and the whole system experiment is done.Finally it draws a conclusion that CBDIM drives have the same performances as the DC dives and the simulation results are in excellent agreement with the experiment according to the experiment under the typical working condition.The CBDIM drives which is firstly developed in China make a contribution to the wide application to some extent in variable speed constant frequency generators and medium voltage ac drive systems in the future.
