The invention relates to a fractional order self-sustaining electromechanical seismograph
system acceleration stability control method with constraints, and belongs to the field of
seismic exploration. The fractional order self-sustaining electromechanical seismograph
system acceleration stability control method comprises the following steps of: S1, carrying out
system modeling, which is implemented by establishing a
mathematical model of a fractional order self-sustaining electromechanical seismograph system according to a Newton's second law and a Kirchhoff's law, and defining constraint conditions; S2, and designing an acceleration stability controller, wherein the design is implemented by constructing an acceleration feedforward controller and an optimal
feedback controller, the acceleration feedforward controller is integrated by a molding behavior function based on a fractional order inversion method, a fuzzy
wavelet neural network and a tracking
differentiator, and the optimal
feedback controller is formed by fusing a fuzzy
wavelet neural network and an adaptive
dynamic programming strategy. According to the fractional order self-sustaining electromechanical seismograph system acceleration stability control method, the boundness of all signals of a closed-loop system is ensured, the
safe operation of the system under the constraint condition is ensured, and meanwhile,
chaotic oscillation can be suppressed and a minimum cost function can be realized.
