Abstract

The invention discloses an electric automobile magnetic suspension flywheel battery zero-power consumption decoupling controller based on a dynamic model. The controller comprises a composite controlled object, a fuzzy neural network inverse dynamic switching model based on a soft set theory method, a linear closed-loop controller and a zero-power consumption control module, output of the linear closed-loop controller serves as input of the fuzzy neural network inverse dynamic switching model based on the soft set theory method, output of the fuzzy neural network inverse dynamic switching model based on the soft set theory method serves as input for controlling the composite controlled object, output of the composite controlled object acts on a magnetic suspension flywheel battery dynamicmodel, input of the zero-power consumption control module is from output of the magnetic suspension flywheel battery dynamic model and the fuzzy neural network inverse dynamic switching model based onthe soft set theory method, and output of the zero-power consumption control module acts on the linear closed-loop controller. According to the controller, translation and rotation modes are decoupled, the zero-power consumption control module is introduced for a decoupled system, and power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of electric drive control equipment, in particular to a zero-power consumption decoupling controller for a magnetic levitation flywheel battery for an electric vehicle based on a dynamic model. Background technique [0002] The maglev flywheel battery is a high-efficiency, clean, mobile secondary discharge device that stores mechanical energy instead of storing electrical energy. The use of non-contact rotating flywheels to store energy has the advantages of high energy density, high energy conversion efficiency, small size, light weight, and long service life. Therefore, it provides a new way to solve the problem of power battery storage for new energy vehicles that is increasingly concerned. [0003] The maglev flywheel battery is a multivariate and multi-coupling complex nonlinear system that integrates multidisciplinary fields. When the maglev flywheel battery is applied to new energy vehicles, changes i...
