Maximum torque per ampere and maximum power per ampere sliding mode control for interior permanent magnet synchronous motors

Abstract

This paper presents novel maximum torque per ampere (MTPA) and maximum power per ampere (MPPA) sliding mode control (SMC) approaches for interior permanent-magnet synchronous motors (IPMs). We first derive the first-order SMC methods to improve the field-oriented control's resiliency against the external perturbations, extraneous noise and modelling uncertainties. After that, we propose the higher-order SMC to significantly reduce the chattering phenomenon, which is inherent in the first-order sliding mode method. Based on the comparison studies, the conventional proportional-integral-derivative based field oriented control shows sluggish response and is more sensitive to parameter perturbations and external torque disturbances. By introducing the novel SMC methods, both the speed and torque regulation performance of interior permanent magnet synchronous motor can be greatly improved. Computer simulation studies have demonstrated the superior performance of the first-order and higher-order sliding mode controllers for interior permanent magnet synchronous motor speed and torque regulation applications.

Designing of an Enhanced Fuzzy Logic Controller of an Interior Permanent Magnet Synchronous Generator under Variable Wind Speed

“…Grounded on average torque and ripple, an impact in the rotor geometry on the device’s performance is made by employing a rotor configuration specified by various pole flux barriers [ 15 ]. The IPM generator with reluctance torque is the prominent design, along with the total output torque contributed by PM [ 16 ]. The TR is abolished to a better level by short-pitching the winding by a few slots to diminish low-order MMF space harmonics, as illustrated in previous research [ 17 ].…”
