Abstract

The invention discloses a mutually-coupled fractional-order chaos electromechanical transducer acceleration adaptive fuzzy control method. The method comprises the following steps: a) creating a smallnetwork formed by three same electromechanical transducers, wherein each electromechanical transducer has a nearest neighbor coupling structure, and building an electromechanical coupled transducer model with a nearest neighbor based on the small network; and b) designing a controller composed of a feedforward fuzzy controller and an adaptive optimal feedback controller, wherein the feedforward fuzzy controller is integrated by a regression non-single-valued type-2 sequence fuzzy neural network, a velocity function and a tracking differentiator in an inversion control framework, and the adaptive optimal feedback controller is formed by the regression non-single-valued type-2 sequence fuzzy neural network, policy iteration and an execution-evaluation reinforcement learning algorithm, and can solve a Hamilton-Jacobi-Bellman equation. The method not only guarantees boundedness of all signals, realizes chaos suppression and synchronous and accelerated convergence, but also minimizes a cost function.

Description

technical field [0001] The invention relates to a control method of an electromechanical transducer, in particular to an accelerated self-adaptive fuzzy control method for a mutual coupling fractional chaos electromechanical transducer. Background technique [0002] In recent years, complex networks with interactions between topological complexity and dynamic properties of coupled elements have gained attention in engineering. With the development of MEMS, research fields such as design, analysis, modeling and control of coupled electromechanical systems have received extensive attention and this trend is gradually increasing. Electromechanical transducers are moving-coil electromechanical devices whose dynamics with associated chaos and bifurcations can destabilize the system. Pérez-Molina and Perez-Polo discuss the nonlinear dynamics of electromechanical transducers composed of ferromagnetic moving parts under the action of harmonic oscillations. The dynamics and synchro...
