Abstract

The invention discloses a method for constructing a decoupling controller of an ironless outer rotor bearingless permanent magnet motor, which comprises a composite controlled object including an iron coreless outer rotor bearingless permanent magnet synchronous motor, and adopts the least squares support vector machine to add 2 Integrators and 3 transfer functions are constructed to form the generalized inverse of the least squares support vector machine. The generalized inverse of the least squares support vector machine and the compound controlled object are connected in series to form two displacement integral pseudo-linear subsystems and a rotational speed integral type. A pseudo-linear system composed of pseudo-linear subsystems, an anti-disturbance closed-loop controller composed of a pre-filter and a displacement regulator is designed for the pseudo-linear system, and the use of the pre-filter in the anti-disturbance closed-loop regulator makes the motor decoupling control. The input signal of the controller is smoother, avoiding the influence of the step signal and the impact signal, so that the output can better follow the command signal. Due to the better following effect, the bandwidth of the controller is significantly improved, thereby improving the performance of the motor decoupling controller. Control performance.

Description

technical field [0001] The invention belongs to the technical field of electric drive control equipment, in particular to a construction method of a decoupling controller of an ironless outer rotor bearingless permanent magnet synchronous motor, which is suitable for high-performance control of an ironless outer rotor bearingless permanent magnet synchronous motor. Background technique [0002] Ironless outer rotor bearingless permanent magnet synchronous motor is a new type of motor that applies bearingless technology and ironless technology to ordinary outer rotor permanent magnet synchronous motor. The bearing winding coil and the stator winding of the motor are stacked together to realize the bearingless of the motor, and the stator material of the motor is replaced from the original magnetically permeable material to a non-magnetically permeable material to realize the coreless of the motor. The ironless outer rotor bearingless permanent magnet synchronous motor not onl...
