The invention belongs to the technical field of vehicle dynamics, and discloses a linear motor energy feedback type active suspension actuator and a control method thereof.The actuator comprises an upper mounting part and a lower mounting part, the upper mounting part comprises an upper outer-layer sleeve and an upper inner-layer sleeve which are concentrically arranged, and the lower mounting part comprises a lower sleeve and a guide column; the upper outer sleeve and the upper inner sleeve can respectively penetrate into the space between the upper outer sleeve and the upper inner sleeve and into the upper inner sleeve; outer-layer annular electromagnets and inner-layer annular electromagnets which are in one-to-one correspondence are arranged on the inner surface of the upper outer-layer sleeve and the outer surface of the upper inner-layer sleeve respectively, a plurality of permanent magnet rings are correspondingly arranged on the lower sleeve and can be matched with the outer-layer annular electromagnets and/or the inner-layer annular electromagnets, and the permanent magnet rings can be matched with the outer-layer annular electromagnets and/or the inner-layer annular electromagnets according to the direction of current in the outer-layer annular electromagnets and/or the inner-layer annular electromagnets. And the lower mounting part can be controlled to move in the upper mounting part. When the outer-layer or inner-layer annular electromagnet breaks down, the supporting effect can still be achieved.
