K and U.S. and in a very small measure in some other countries This interest has been primarily due to the emerging markets for variable speed drives in consumer and industrial products, such as home appli ances, air conditioning, hand tools, fans, pump motor drives, extruders, and auto- motive and railway accessory drives. These new applications for variable speed drives are very cost sensitive while demanding higher reliability and an equivalent perfor- mance of dc and induction motor drives at the minimum. Srm drive systems promise to meet such demands in some select high-volume applications, hence the spurt of activity in this field The expansion of know ledge in this field has been great, and it is timely to summarize in this book some of the key results in modeling, simulation, analysis, and design procedures for srMs; their converter topologies system integration; control techniques with and without position sensors; the much talked-about noise issue; and, finally, their applications. With that perspective, this book has been in preparation for the last 12 years, and the material has been taught in a number of IEEE forums, at industrial sites, and at the graduate level at the authors university and at Padova University inl Italy The book presumes a familiarity with fundamentals of electromechanics, intro ductory power electronics, and linear control system theory all at the undergraduate level. The intended audience for the book is electrical engineers in industrial and federal laboratories and students at the senior/graduate level in universities. tradi tional trappings of worked examples and exercise problems are done away with, as this subject demands complete immersion and therefore much more intensive study and initiative to do extensive work by the readers on their own. The book is organized as follows Chapter 1 contains the introduction to SRM, its principle of operation, various types of SRM configurations including linear SRM, and the equivalent circuit Chapter 2 discusses the magnetic equivalent circuit derivation and an analytical approach to the evaluation of the key three-dimensional relationships among Aux linkages, excitation current, and rotor position in the srm. The nonlinear materia characteristics are preserved in this approach. These machine characteristics are central to the analysis and design of srms Chapter 3 contains an analytical design procedure for the srm based on the output power equation that is prevalent in the design of electrical machines. The resistive and core losses for thermal consideration criteria for the selection of stator and rotor back iron thickness, pole height, number of phases, ratio of pole arc to pole pitch, self-starting requirements to be fulfilled in the design, inductance mea surement, and design of linear SrM from an equivalent rotary srM are addressed f o838_Frame_FM. im Page vi Monday, May 21, 2001 6: 47 AM rom fundamentals. Steady-state computation of air gap torque is also derived in this ch Converters and their classification, principle of operation, design considerations and merits and demerits of each converter and their impact on the machine output form the core of Chapter 4. Converters that have some merit from the point of view of industrial applications are considered in this selection The converter. sRM. and load are integrated through a controller The basic drive system control is developed and illustrated with an implementation to demonstrate the similarity of this drive to dc and ac drives The inadequacy of such controllers for high-performance applications is discussed, and contributing factors are identi fied. The heart of a high-performance system is current control, and various methods of current control such as the conventional linearized controller, linearizing and decoupling controller, and hybrid controller are systematically derived and devel- oped. An alternative to current control is the flux linkages control, and its merits and demerits are discussed. The torque controller to produce very little torque ripple using torque distribution function-based control is introduced and its performance is studied in detail. Finally, analytic derivations of the speed controller gain and time constants are made using the symmetric optimum method. Throughout this chapter, an analytical approach is emphasized to understand the relationship between machine parameters and output variables. USually the literature neglects mutual coupling in performance prediction. It is shown in the text that its omission may lead to as much as 6% torque ripple even in very good machine designs. Methods to include mutual coupling effects in performance prediction and in the linearized and decoupled current controller, flux linkage controller, and torque controller designs are presented Dynamic modeling, simulation, and analysis play crucial roles in the drive system analysis and design and are considered in Chapter 6. The subsystems mod- eling and their integration are developed step by step The simulation procedure is illustrated with results to enhance the understanding of the srm drive The srm drive has been plagued with the acoustic noise problem. To understand this issue the sources of acoustic noise are explained in Chapter 7. Measures to mitigate noise from magnetic, mechanical, aerodynamic, and electronic sources are presented. Active noise cancellation techniques using the power converter control are also described. a brief summary of qualitative measures to reduce noise is given In order to facilitate noise quantification in laboratories, an introduction to measure ment is included in this chapter. The necessity for absolute rotor position information in Srm drives increases the complexity of motor manufacture, with the mounting of position sensors resulting in higher costs compared to other drives that do not require rotor position sensors for their operation, such as dc and ac motor drives. various electronic methods for estimating or predicting the rotor position information are discussed along with their algorithms in Chapter 8. These methods are not invasive mechanically and use only the voltage applied across the winding and the current fowing in it. many of the methods discussed in the literature are classified and their implementations are discussed to enable readers to assess the suitability of a particular method in the context of an application. Low-cost current sensing to obtain a completely sensorless SRM drive systen is also included ⊙2001 by crc Press LLC f o838_Frame_FM. im Page ix Monday, May 21, 2001 6: 47 AM Application considerations and particular applications of the srm drive systems are described in Chapter 9. The Srm drive system is reviewed for merits and demerits in regard to each of its subsystems. By doing so, the strengths and weaknesses of the sRM drive hecome apparent and hence their suitability for a given application. appl cations are discussed in terms of the power categories of low, medium, and high and high-speed drives. Emerging applications in the high-volume, underwater, and linear drive areas, particularly in machine tool drives, are identified This book contains significant results from my research students, past and present They are Prof. R.
