Abstract

The invention discloses an ARM+DSP-based intelligent structure control system, which comprises a first piezoelectric acceleration sensor, a magneto-rheological elastomer vibration isolator, a second piezoelectric acceleration sensor, a charge amplifier, a voltage-stabilization direct current source, a DSP controller and an ARM processor. The two sensors respectively obtain an excitation signal and a response signal. The charge amplifier is used for filtering and amplifying signals. The DSP controller is used for conducting performing the A / D treatment and the FFT transformation on an analog voltage signal and controlling the on / off state of a relay module by using an on / off control algorithm so as to control the coil current of the magneto-rheological elastomer vibration isolator and change the rigidity and the damping of the magneto-rheological elastomer, so that the active-passive integrated intelligent vibration isolation is realized. The ARM processor is used for running an intelligent structure control interface, inputting vibration isolation parameters and calculating an on / off control threshold value. The ARM processor and the DSP controller are in SCI duplex communication with each other, so that parameters are transmitted between the ARM processor and the DSP controller. According to the invention, the magneto-rheological elastomer vibration isolator is intelligently controlled. Meanwhile, the functions of running state display, parameter input and the like are realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent structure control, in particular to an intelligent structure control system based on ARM+DSP. Background technique [0002] Magnetorheological materials are a general term for a class of smart materials whose rheological properties can be controlled with an applied magnetic field. Magnetorheological elastomer is a new member of this class of materials, which is composed of soft magnetic particles and polymer matrix, and its typical feature is that the shear modulus and compressive modulus can be controlled by an external magnetic field. The magneto-rheological elastomer vibration isolator developed by it has the advantages of simple structure, fast response, strong reliability, wide operating frequency range, and low energy consumption. It has become a new generation of semi-active vibration isolators. The application prospect is very broad. As an intelligent structure, whether the magnetorh...
