Intelligent marine upright column system based on PID controlling method

Abstract

The invention belongs to the technical field of intelligent structure controlling, and particularly relates to an intelligent marine upright column system based on a PID controlling method. The intelligent marine upright column system comprises a piezoelectric accelerometer sensor, a charge amplifier, an upright column structure, a magnetorheological damper and a PID controlling processing system,the piezoelectric accelerometer sensor is used for obtaining a vibration response signal, and the charge amplifier is used for filtering waves and amplifying signals; the PID controlling processing system is used for generating a controlling signal after comparing a collected response signal with target requirements, so that the coil current size of the magnetorheological damper is controlled, the damping force size of the magnetorheological damper is changed accordingly, and active and intelligent vibration isolation is achieved; and the PID controlling processing system can achieve modification of controlling objectives and controlling parameters of the PID controlling processing system through a laptop, the fact that the vibration response of the plate frame structures at both ends ofan upright column is controlled through the intelligent marine upright column system based on the PID controlling method is achieved, and the multiple functions such as operation state displaying andparameter inputting are achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent structure control, and in particular relates to a marine intelligent column system based on a PID control method. Background technique [0002] Vibration damping performance is an important index to measure the overall performance of modern ships. Active vibration control technology has become a research hotspot at home and abroad because of its strong adaptability, good control effect and many other advantages. [0003] Magneto-rheological damper, as an intelligent damping component that has developed rapidly in recent years, has been well evaluated in the field of vibration damping because of its good damping performance, and has a very good application prospect. Magnetorheological fluid is a mixed fluid composed of non-magnetic carrier liquid, magnetic medium particles with high conductivity and low hysteresis, and surfactant. Its typical feature is that the shear modulus and compression ...
