Abstract

The invention relates to a semi-active fuzzy control method, and aims at solving the existing problems that the selection of parameters of a control system is difficult and parameter optimization is not comprehensive of fuzzy control in semi-active control based on a magnetorheological damper. The invention provides the semi-active control algorithm which combines and improves a crow searching algorithm and the fuzzy control, seismic response is taken as the input of improving a fuzzy controller, and therefore the fuzzy controller is allowed to directly output control signal. The comprehensiveoptimization of key modules of the fuzzy control system is achieved on the basis that an original crow algorithm is improved. The method has the advantages that a voltage signal of the magnetorheological damper can be accurately controlled to achieve the full shock-absorbing performance of the magnetorheological damper so that the vibration of a building structure under seismic excitation can besignificantly inhibited, and the seismic response can still be effectively reduced when a seismic wave and structural parameters change.

Description

technical field [0001] The invention relates to the field of semi-active control, in particular to a semi-active fuzzy control method. Background technique [0002] Earthquake is a natural disaster that seriously threatens the safety of human life and property. How to continuously improve the anti-seismic performance of civil structures to ensure the safety of the structure itself and the safety of people and property inside is an urgent mission with important realities. significance. The magnetorheological damper is an intelligent semi-active control device, which has the advantages of both active control devices and passive control devices, and has become a research hotspot in semi-active control devices. However, due to the complex constitutive relationship of the magnetorheological fluid in the magnetorheological damper, the damping force has complex nonlinearity. Aiming at the shock absorption requirements of building structures based on magnetorheological dampers, in...
