摘要:永磁同步电机作为高效电机的代表,在中小功率、高精度、高可靠性、宽调速范围的伺服系统应用领域逐步推广。然而永磁同步电机是一个强耦合、非线性、变参数的复杂对象,针对传统PI控制器无法满足的永磁同步电机伺服系统的高性能要求的问题,采用仿人智能控制方法,在(e-e•)相平面设计理想轨迹曲线,设计了特征模型集、控制模态集及推理规则集,仿真实验结果表明,仿人智能控制方法永磁同步电机转速调节过渡过程的平稳性和q轴电流脉动等指标均优于传统PI调节器。

Otherwise,because traditional PI controller can not satisfy the highperformance of PMSM servo system,Human Simulated Intelligent Control(HSIC) method was used in this system, ideal trajectory was designed in e-e• phase plane. Characteristic model,control modality,inference regulation were used in HSIC algorithm. Simulation experiment proved that HSIC algorithm had more steady and less qaxis current pulse to PI control in the transition procedure of PMSM governing.
