In a control apparatus for a rotating electric machine, a phase feedback gain is set such that first and second conditions are met. The first condition is that gain margin and phase margin in frequency characteristics of a first loop transfer function are ensured. The second condition is that a gain intersection angular frequency in frequency characteristics of the first loop transfer function is lower than respective resonance angular frequency in frequency characteristics of first and second transfer functions. An amplitude feedback gain is set such that third and fourth conditions are met. The third condition is that gain margin and phase margin in frequency characteristics of a second loop transfer function are ensured. The fourth condition is that a gain intersection angular frequency in frequency characteristics of a second loop transfer function is lower than respective resonance angular frequency in frequency characteristics of third and fourth transfer functions.
