Embodiment Construction

[0049] In this embodiment, a modeling method of an inverse model of a magneto-rheological damper and its application include a modeling method of an inverse model of a magneto-rheological damper, an implementation circuit of the inverse model, and a control circuit of the inverse model. The inverse model of magnetorheological damper establishes the mathematical expression of the inverse model of magnetorheological damper on the basis of the transformation model of Bouc-Wen model, and establishes the relationship between the excitation current and controllable damping force, relative displacement and velocity of magnetorheological damper. The corresponding relationship between them can reduce the hysteresis effect of the controllable damping force of the magneto-rheological damper and the relative displacement and relative velocity of the damper. Integrating the inverse model of the magneto-rheological damper and its control circuit in the semi-active control system based on the...

Abstract

The invention discloses a modeling method of an inverse model of a magneto-rheological damper and its application. Correspondence between magneto-rheological damper excitation current and controllable damping force, damper relative displacement and relative velocity. A control circuit of an inverse model of a magneto-rheological damper, including a realization circuit of an inverse model of a magneto-rheological damper, a drive circuit of a magneto-rheological damper, and a magneto-rheological damper, which jointly constitute a closed-loop control system of a magneto-rheological damper . The invention can simplify the modeling process of the inverse model of the magneto-rheological damper, reduce the error of the damping force of the magneto-rheological damper due to the inherent strong nonlinear hysteresis characteristics, thereby improving the control precision of the damping force.

Description

technical field [0001] The invention relates to the field of vibration control; in particular, it relates to a modeling method of an inverse model of a magneto-rheological damper used as a semi-active actuator in a vibration / shock control system and its application. Background technique [0002] Magneto-rheological damper, a semi-active actuator based on the magneto-rheological effect, has the advantages of low energy consumption, fast response, simple structure, and continuously adjustable damping force. It is an ideal device for implementing semi-active control. It is widely used in various vibration / shock control systems. However, the inherent strong nonlinear hysteresis characteristics of magnetorheological dampers make it difficult to establish an accurate mathematical model and corresponding control system for magnetorheological dampers, which brings great difficulties to the precise control of the damping force of magnetorheological dampers. . [0003] At present, t...
