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...

Problems solved by technology

However, unlike the static electric spindle, the application of the magnetic levitation flywheel battery to the new energy vehicle has more complicated working conditions than that of the electric spindle, that is, the different driving states of the car and various problems caused by the uneven road surface. Vibration will generate dynamic load on the rotor of the flywheel battery, which will affect the stable operation of the rotor of the maglev flywheel battery
