Abstract

The invention relates to a semi-active fuzzy control method. In the semi-active control based on a magneto-rheological damper, in view of the problems of difficulty in selecting parameters of the control system and incomplete parameter optimization in fuzzy control, the invention proposes an improved crow search algorithm And the semi-active control algorithm of fuzzy control, the earthquake response is used as the input of the improved fuzzy controller, so that it can directly output the control signal. On the basis of improving the original crow algorithm, the overall optimization of the key modules of the fuzzy control system is realized. The control method proposed by the present invention can accurately control the voltage signal of the magneto-rheological damper, give full play to the damping performance of the magneto-rheological damper, and significantly suppress the vibration of the building structure under earthquake excitation. It can still effectively reduce the seismic response of the structure even when the structure 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...
