Embodiment Construction
[0016] This patent takes the two-pole floating control four-pole bearingless asynchronous motor as the controlled object, and takes the rotor magnetic field orientation mode of the torque system as an example, proposes an independent inverse system decoupling method for the bearingless asynchronous motor, and simplifies the system model of the bearingless asynchronous motor The complexity of the maglev system avoids the dependence of the inverse model of the maglev system on the magnetic field orientation mode of the torque system. The specific method is, according to the original model of the independent torque system and the original model of the independent magnetic levitation system constructed according to the working principle of the bearingless asynchronous motor, respectively establish the no-load torque variable T L The inverse model of the independent torque system and the air gap flux linkage α, β axis components ψ including the independent torque system 1α and ψ 1...
