摘要：

为改善逆变器在非线性电机负载的情况下输出力矩的对称性,提高动量轮输出力矩精度和转速响应能力,提出了高动态协同控制方法。该方法基于永磁同步电机控制系统,分析了导致动量轮电机力矩不平衡的原因,采用基于四桥臂逆变器的协同控制对不平衡力矩进行动态补偿。明显提高了动量轮系统响应输入力矩的能力。实验结果证明了该方法的有效性,经计算飞轮制动过程力矩不对称度优于2%。

Abstract:

In order to improve the symmetry of the output torque, the torque accuracy and the speed response of the momentum wheel in the case of the nonlinear motor load, a high dynamic cooperative control method was proposed. The unbalanced reasons of momentum motor torque were analyzed which based on the permanent magnet synchronous motor control system. The unbalanced torque was dynamically compensated by the cooperative control based on four-leg inverter. The ability of the momentum wheel system to track the input torque is improved. Flywheel braking process torque asymmetry is less than 2%. The experiments show the validity of the method.

Key words: four-leg inverter, synergetic control, three-dimensional space vector pulse width modulation(3D-SVPWM), permanent magnet synchronous motor(PMSM), momentum wheel
