Abstract：Due to mismatch of output impedances of LC and input impedance of inverter-motor system,inverter-IPMSM(Interior Permanent Magnet Synchronous Motor) system will lose stability with a large output power.That means DC current and voltage oscillation.For stability analysis,input admittance formulas of inverter-IPMSM system under double current control are derived.Reference induction motor system oscillation suppression methods and combined with IPMSM torque formula,two oscillation suppression methods based on d-axis voltage and current command separately are proposed.These two methods are compared with the existing oscillation suppression methods based on q-axis voltage and current command separately.Input admittance formulas of inverter-IPMSM system with oscillation suppression are derived.The Nyquist theorem is adopted to verify the validity of the oscillation suppression methods.According to the motor model and control system model,the oscillation suppression method based on q-axis voltage is considered to be the best.Experimental verification of the viewpoints is carried out.
