Embodiment Construction

[0037] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] The technical solution of the present invention: a structural vibration pole configuration control method based on non-probabilistic reliability optimization. First, an active control closed-loop system of structural vibration pole configuration is established. Then, for the established closed-loop output feedback active control system, an interval estimation method for the eigenvalues ​​of the closed-loop output feedback active control system with interval parameters is proposed. On this basis, a non-probabilistic reliability calculation method for closed-loop output feedback active control systems is established. The output feedback controller is optimized based on the interval estimation method and the non-probabilistic reliability calculation method of the eigenvalues ​​of the closed-loop output feedback active control system with int...

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, and in particular to a control method for the configuration of structural vibration poles based on non-probabilistic reliability optimization. Background technique [0002] Active control of vibration and noise is a rapidly developing new field. The active control technology of vibration and noise involves multi-discipline cross-coupling, has a wide range of application value and academic value, and is the beginning of aerospace structure becoming intelligent. Active vibration and noise control is to eliminate vibration or noise caused by primary interference by introducing secondary interference (vibration or noise). The secondary interference is generated by the driver, and the specific form of the secondary interference is calculated by the controller. The development of active vibration and noise control technology is not achieved overnight, and has been accumulate...
