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。
Permanent Magnet Synchronous Motors （PMSM） as a representative of high efficiency motor is used widely in the area of medium and small-sized power, high-accuracy, high reliability and wide-scope speed governing servo system. Otherwise, because traditional PI controller can not satisfy the high-perform- ance 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 regula- tion were used in HSIC algorithm. Simulation experiment proved that HSIC algorithm had more steady and less q-axis current pulse to PI control in the transition procedure of PMSM governing.
