Abstract

Disclosed in embodiments of the present application are a method and apparatus for determining a rotor state, an electronic device, and a computer storage medium. The rotor comprises N equivalent units; each equivalent unit comprises a disc and a beam; and at least one equivalent unit comprises a bearing. The method comprises: on the basis of a stress state of an i-th disc, determining an i-th disc matrix that characterizes a relationship between state vectors at two ends of the i-th disc, wherein the stress of the i-th disc comprises: a shear force, and an elastic force and a damping force generated by the bearing, N≥2, and N≥i≥1, N and i being integers; on the basis of a bending deformation formula of an i-th beam, determining an i-th beam matrix that characterizes a relationship between state vectors at two ends of the i-th beam; on the basis of the i-th disc matrix and the i-th beam matrix, determining a state relationship between two ends of an i-th equivalent unit; on the basis of a Likati Riccati transformation relationship and the state relationship between the two ends of the i-th equivalent unit, determining state vectors of the N equivalent units that characterize a state of the rotor.
