Almost all authors that have implemented current vector control of interior permanent magnet synchronous motors, need to compensate the nonlinear effects characterizing such machines due to saturation and air-gap flux redistribution. In this paper, with the intent of offering an analytical approach to the control laws that govern any optimized operation of the motor on a wide speed range including field-weakening, a nonlinear model of the IPM machine is introduced and adopted as the tool to deduce the control equations. Experimental tests are performed on a IPM machine to show the non linearities, to model them accurately, and to check the validity of the proposed control techniques.

Abstract
Almost all authors that have implemented current vector control of interior permanent magnet synchronous motors, need to compensate the nonlinear effects characterizing such machines due to saturation and air-gap flux redistribution. In this paper, with the intent of offering an analytical approach to the control laws that govern any optimized operation of the motor on a wide speed range including field-weakening, a nonlinear model of the IPM machine is introduced and adopted as the tool to deduce the control equations. Experimental tests are performed on a IPM machine to show the non linearities, to model them accurately, and to check the validity of the proposed control techniques.File | Dimensione | Formato | |
