Field oriented control (FOC) has become the most widely used method of permanent magnet synchronous motor because of its good decoupling, small torque ripple and easy realization. Current loop parameter design is the key of field oriented control. In this paper, the relationship between the control parameters and the performance of current control is deduced with the method of transfer function analysis. The optimal selection principle of control parameters is given.
