Parameter identification and self-commissioning of AC permanent magnet machines - A review

Abstract

Parameter identification of permanent magnet synchronous machines is a topic of utmost interest these days. The growing effort and investment in this field of research is largely due to the ever-expanding market share of these machines. The high-performance and efficient control of the drive depends on the accuracy with which the information about the machine connected to its terminals is available. The available identification methods are surveyed here and they are classified into offline and online strategies. Self-commissioning, in principle, is a subset of offline methods, yet it is treated separately for its importance in modern adjustable speed drives that tend to minimize the user intervention. Fully exploiting the power electronic converter and the computational power on-board a modern drive, the self-commissioning feature can be embedded in the start-up routine of the drive to estimate the parameters of the machine at hand. This paper presents a review of the parameter identification techniques and schemes investigated over the past few decades.

Parameter Identification and Self-Commissioning in AC Motor Drives: A Technology Status Review

“…For IMs, this paper will particularly focus on parameter identification methods that are not reported in [16]. As far as the PMSMs are concerned, the literature does not report any detailed survey except [17], which presented the state-of-the-art up to the year 2015. This paper will include some of the works cited in [17] to give a complete panorama of the parameter identification of PMSM machines besides reviewing SyRMs' identification methods.…”

“…As far as the PMSMs are concerned, the literature does not report any detailed survey except [17], which presented the state-of-the-art up to the year 2015. This paper will include some of the works cited in [17] to give a complete panorama of the parameter identification of PMSM machines besides reviewing SyRMs' identification methods. The authors believe that when the presented survey is read in conjunction with [16], the reader gets a complete picture of the parameter identification and self-commissioning methods of ac machines operated through power electronic converters.…”

Identification of Three-Phase IPM Machine Parameters Using Torque Tests

“…The techniques investigated in the literature estimate machine parameters either analytically (from the design data) or through experimental tests. A brief survey of different parameter identification methodologies can be found in [14].…”

Sensorless magnetic model and pm flux identification of synchronous drives at standstill

“…This method is very accurate, but requires a dedicated test rig and off-line identification of each new machine. In recent years, several self-commissioning techniques have been proposed [4].…”
