五相永磁同步电机的变饱和柔性变结构控制

五相永磁同步电机因其可实现低压大功率、高可靠性、低电压直流供电、输出转矩脉动小等优点,在航空、舰船推进、电动汽车和高速电梯等领域得到了广泛应用。将其解耦,分别得到能量转化空间和广义零序空间,引入了柔性变结构的控制策略,设计了一种变饱和变结构控制器。仿真和实验结果表明,替代传统PID控制的柔性变结构五相永磁同步电机控制系统响应速度更快,转矩脉动更小。

Variable Saturation Soft Variable Structure Control in Five-Phase Permanent Magnet Machines

Due to the low voltage and high power, high reliability, low voltage DC power supply, output torque ripple small ,five phase PMSM has been widely used in areas such as aviation, ship propulsion, electric cars and High speed elevator .In order to get five phase induction motor vector control model, the five phase PMSM was divided into electronic mechanical energy conversion space and the generalized zero sequence space.In order to meet the control requirements ,we introduce a new control strategy named variable saturation and soft variable Structure.Based on control scheme,a variable saturation variable structure controller was designed. Simulation and experimental results are presented that the variably saturated variable structure of five phase PMSM control system,compared to the traditional PI control system,have faster response speed, small torque ripple .
