Abstract

The invention relates to an adaptive neural network optimal timing synchronization control method for a unidirectional coupling fractional order self-sustaining electromechanical seismograph system, and belongs to the field of seismograph system synchronization control. The method comprises the following steps: establishing a synchronization model of a one-way coupling fractional order seismograph system; and designing a controller: firstly, adopting a specified performance function and a constraint condition to ensure transient and synchronous performance of the system, adopting an interval type-2 fuzzy neural network with transformation to estimate an unpredictable function of the one-way coupling fractional order self-sustaining electromechanical seismograph system, establishing a fractional order hyperbolic tangent tracking differentiator to process the complexity of a performance function and a fractional order, minimizing a cost function to make a tracking error fall into a specified constraint region, then designing the adaptive neural network optimal timing synchronization controller in an inversion recursion form, and finally, ensuring that all signals of the closed-loop seismograph system are bounded by using a Lyapunov function and a timing stability criterion.

Description

technical field [0001] The invention belongs to the technical field of synchronous control of seismograph systems, and relates to an adaptive neural network optimal timing synchronous control method for a one-way coupling fractional-order self-sustaining electromechanical seismograph system. Background technique [0002] Self-sustaining electromechanical seismograph systems with complex dynamics are sensitive instruments that record ground motions and waves propagating at certain frequencies. Its fractional-order modeling can more accurately describe the real motion process of engineering objects than integer-order modeling. One-way coupled fractional order seismograph systems have complex nonlinear dynamics, gyro coupling, unpredictable functions, predetermined constraints, and timing convergence. Therefore, it is important and challenging to achieve optimal timing synchronization control between the driving seismograph and the responding seismograph. [0003] Synchroniza...
