“…In [16] Espinosa et al adaptively tune Fourier coefficients for periodic torque ripple minimization. In [18] a method to reduce torque ripple by updating the current reference is presented. This has the drawback in that the current controller is unable to compensate harmonics at high motor speed due to the bandwidth of the controller.…”

This work presents a method to automatically generate a high performance controller for the permanent magnet synchronous motor (PMSM). The method consists of two components, a nominal system identification and a harmonic component identification. Both identification methods are based on dynamic mode decomposition (DMD). The nominal system identification is used to assign the feedback gaines by matching the desired closed-loop eigenvalues and eigenvectors. The harmonic system identification is used to generate vectors that are multiplied by a delay embedding of the current to predict harmonic components at the next time-step. The method is applied to two experimental test setups, one interior permanent magnet (IPM) and one surface mount permanent magnet (SPM) motor. It is shown that the automatically generated feedback controller is able to achieve a more precise transient response than the traditional rule-based PI controller. It is also shown the harmonic compensation method is able to reduce total demand distortion (TDD) on phase currents better than a traditional adaptive filter approach without the need for gain tuning. This work shows a novel approach to using DMD for the complete system identification of the PMSM, and lays the foundation for using DMD with delay embeddings to analyze and manipulate harmonic signals in a predictive way.

“…However, it is not possible to calculate the starting torque, since the output power should be divided by zero speed. The mechanical power method can also be used for other electrical machines [5,6,7]. However, it is not possible to estimate the cogging torque using this method.…”

This contribution introduces a vector interpretation to unify the description of torque development in rotating electrical machines. The motivation behind this attempt is the necessity of applying different physical interpretation and calculation methods, such as Lorentz force, Maxwell stress tensor, coenergy methods etc., for predicting and estimating different torque components, e.g. synchronous torque, oscillating torque, cogging torque, reluctance torque etc., in different rotating electrical machines. The unified vector model describes and estimates the different torque components in rotating electrical machines with an apprehensible concise formulation. Beyond that, the other most frequently used tools and terms in the field of electrical machines, such as Park and Clark transformations, phasor diagram etc., can be derived directly from this model, which has also a simplifying didactic contribution to a conventional course of electrical machines.
