Structural vibration pole assignment control system design method based on non probabilistic reliability optimization

Abstract

The invention relates to a structural vibration pole assignment control system design method based on non probabilistic reliability optimization. The method comprises steps: firstly, an active control closed loop system for structural vibration pole assignment is built; then, a non probabilistic reliability calculation method for a closed loop output feedback active control system is built, and based on an interval estimation method for a closed loop output feedback active control system characteristic value containing an interval parameter and the non probabilistic reliability calculation method, an output feedback controller is optimized; and finally, an output feedback control system based on pole assignment meeting the reliability requirements is obtained. Parameters of the output feedback controller are determined from the point of view of reliability, the problem of uncertainty existing in the traditional structural vibration pole assignment output feedback controller design process is thus solved, and thus, the closed loop control system obtained based on pole assignment can meet design requirements in a parameter perturbation condition.

Description

technical field [0001] The invention relates to the technical field of active control of structural vibration, in particular to a design method of a structural vibration pole configuration control system based on non-probabilistic reliability optimization. Background technique [0002] Active control of vibration and noise is a new and rapidly developing field. The active control technology of vibration and noise involves multi-disciplinary cross-coupling, has extensive application value and academic value, and is the beginning of the intelligentization of aerospace structures. Vibration and noise active control is to eliminate the vibration or noise formed by primary disturbance by introducing secondary disturbance (vibration or noise). The secondary disturbance is generated by the drive, and the specific form of the secondary disturbance is calculated by the controller. The development of vibration and noise active control technology is not achieved overnight, but also a...
