Variable Speed Drive Characterization: Review of Measurement Techniques and Future Trends

Abstract

The significant advances in power electronics have permitted the implementation of sophisticated methods for control of electric motors. Each innovative electrical apparatus for industrial and automotive application must be correctly and exhaustively tested, both during the developing process and finally for the compliance test. The development of a new electrical system should be associated with a parallel design of an ad hoc measurement system, whose performance should be defined according to the features of the system under test. In recent years, the increasing interest for sensorless electric motor drives involved the development and implementation of a wide set of control techniques. This paper reviews the state and the trends of measurement techniques and instruments applied for the experimental characterization of variable speed drives.

Estimation of speed, armature temperature, and resistance in brushed DC machines using a CFNN based on BFGS BP

“…A more modern method can be found in [12,16], but the temperature measurement gave rise to two major * Correspondence: h.mellah@univ-chlef.dz problems: optimum sensor placement and the difficulty of achieving rotor thermal measurements. Likewise, speed measurement can also be difficult [17]. Moreover, information from sensors installed on rotating parts leads to techno-economic difficulties in the measurement chain.…”

“…The DC motor speed controllers frequently use feedback from a speed measuring device, such as a tachometer or an optical encoder [1,2], but this later, adds an additional cost and congestion throughout the installation [2,3], the problems related to the speed measurement are detailed in the [3].…”
