Maximum Power Control of IPMSM Considering Nonlinear Cross-Magnetization Effects

Abstract

-Interior permanent magnet synchronous motor is widening its application compared to other AC machines because of magnetic and reluctance torque. Despite of the advantages, improving control performance with parameter nonlinearity consideration is crucial during the field weakening control. This paper shows a maximum power control method at the field weakening region that considers d, q inductance's nonlinearity due to magnetic saturation and d, q mutual inductance. To verify the feasibility of control scheme, FEM simulations and experiments about comparison between linear and nonlinear maximum power control are carried out.

Improved neuroendocrine intelligent control for a permanent magnet linear synchronous motor

“…And PID control based on genetic algorithm requires the establishment of precise model of the control object, which is hard to achieve in practical engineering applications. [10][11][12] Bio-intelligent control is a starter intelligent control strategy that was developed fairly recently. Its theoretical basis is the operating mechanism of human physiological systems, such as the nervous system, endocrine system, immune system, and genetic mechanism.…”

Neuro-Fuzzy Control of Interior Permanent Magnet Synchronous Motors: Stability Analysis and Implementation

“…For a fair comparison, the observer-based FLC scheme in [2], which consists of the control structure similar to the proposed observer-based NFC algorithm, is adopted in this paper. The control inputs (V qs and V ds ) are represented by …”

“…The permanent magnet synchronous motor (PMSM) has been extensively used in variable-speed motor drives such as electric vehicles, home appliances, military or medical equipment, machine tools, and industrial robots because of its wide speed range operation and high power density [1][2][3][4]. Depending on the position of the permanent magnet on the rotor, the PMSM can be mainly classified into two types: surface-mounted PMSM (SPMSM) and interior PMSM (IPMSM).…”
