Abstract

The invention, which belongs to the field of automation, relates to an optimal synchronous control method of a coupled fractional order chaotic electromechanical device. A synchronous model of a fractional-order electromechanical device with mutually coupled capacitance and resistance is established, and a phase diagram shows that dynamic behaviors of the fractional-order electromechanical deviceare closely related to physical parameters, coupling coefficients and fractional orders. In order to transfer a driven system from an original track to a track of a driving system, the invention provides an optimal synchronous control method consisting of a self-adaptive feedforward controller and an optimal feedback controller. The invention provides a feedforward controller for estimating an unknown function of a dynamic system under a framework combining a fractional order backstepping method with a hierarchical 2-type fuzzy neural network. Meanwhile, an adaptive dynamic planning method isprovided to solve the zero and differential game problem in the optimal feedback controller. According to the invention, asymptotic stability of a closed-loop system is ensured, optimal synchronization is realized, and a cost function is minimized.

Description

technical field [0001] The invention belongs to the field of automation and relates to an optimal synchronous control method for coupled fractional-order chaotic electromechanical devices; Background technique [0002] MEMS are widely used in milling, seaming, tamping and compaction of mixers, vibrating screens, vibrating hammers and various devices. Depending on the application of the electromechanical device, the chaotic oscillations of the electromechanical device have positive and negative effects in relation to productivity. For the synchronous control problem that people care about, it is very challenging to drive multiple electromechanical coupling devices to complete a given task periodically or chaotically. [0003] In order to reveal the dynamic characteristics of electromechanical devices and facilitate the subsequent synchronous control, previous research results are provided and the proposed research work is distinguished. Tausiff et al. analyzed the dynamic p...
