| Abstract |
This paper proposes a controller design method for suppressing the resonance generated in
the slave motor in the middle and low speed operation range, according to the load and parameter
differences between two motors, during parallel operation using the master and slave method that
controls two surface permanent magnet synchronous motors connected in parallel by a single inverter.
The proposed resonance suppression controller is directly obtained by analyzing the resonance
characteristics, using the lead controller method. Therefore, it is possible to fundamentally reduce trial
and error to set the controller gain. In addition, because the proposed resonance suppression controller
was designed as a lead controller, the stability region of the system increased owing to the added zero
point, making the system robust with respect to parametric variations. Simulations and experiments
confirmed the usefulness of the proposed method and the system¡¯s robustness with respect to
parametric variations. |
