| 摘 要： | 将双级矩阵变换器(two-stage matrix converter,TSMC)作为感应电机的驱动装置,针对传统矢量控制中感应电机参数变化造成控制系统解耦不充分的问题,提出了基于合成矢量的TSMC驱动感应电机电流控制策略。对TSMC与感应电机合成矢量的数学模型进行推导和合理的简化。利用合成矢量根轨迹法设计出一种基于复数比例–积分控制器的电流闭环控制系统,解决了随着系统频率增加控制系统控制性能大大下降的问题,并降低了常规解耦控制系统对电机参数的依赖性。仿真结果表明:TSMC能提供满足感应电机调速要求的高质量输出电压和电流,所提出的控制策略能有效改善控制系统的动态和稳态性能。

| Abstract: | To solve the problem that in traditional vector control the decoupling of control system is insufficient due to parameter variation of induction motor, two-stage matrix converter (TSMC) is utilized as the driver of induction motor and a current control strategy for induction motor fed by TSMC based on complex vector is proposed. The mathematical model for complex vectors of induction motor and TSMC are derived and rationally simplified. Using root locus method of complex vectors, a complex PI controller bas... |
