Introduction Therefore, the following thesis can be formulated: “In the view of commercial manufacturing process the most convenient control scheme for voltage source inverter-fed permanent magnet synchronous motor (PMSM) drives is direct torque control with space vector modulator (DTC-SVM)”. To prove the above thesis, the author used methodology based on an analyze and simulation as well as experimental verification on the laboratory setup with 3kW PMSM motor. Moreover, the presented control algorithm DTC-SVM has been introduced and used in serial commercial product of Polish manufacture TWERD, Toruń. In the author’s opinion the following results of the thesis are his original achievements: • development of a simulation algorithm in SABER package for the investigation of PWM inverter-fed PMSM control, • elaboration and experimental verification of digital flux and torque controller design based on the Z-transform approach for series (cascade) and parallel structure of DTC-SVM schemes, • implementation and verification of series (cascade) and parallel DTC-SVM schemes on experimental laboratory setup with 3kW PM synchronous motor drive controlled by floating point DS1103 board. • bringing into production and testing of developed DTC-SVM algorithm in Polish industry. The thesis consists of eight chapters. Chapter 1 is an introduction. In Chapter 2 mathematical model of PM synchronous motor and his basic control modes are presented. Chapter 3 is devoted to voltage source inverter, his nonlinear characteristics and different PWM techniques. Chapter 4 gives brief review of PM synchronous motor control method such as FOC and classical DTC. In Chapter 5 two kind of DTC-SVM control schemes are presented. Also, the analysis and synthesis of digital flux, torque and speed controllers based on Z transform approach are given. Chapter 6 is devoted to initial rotor detection methods, stator flux vector and rotor speed estimation algorithms. In Chapter 7 experimental results are 6
Introduction presented and studied. Chapter 8 includes the finally conclusions. Description of the SABER based control algorithm, basic coordinate transformations and parameters of used PM synchronous machine as well as inverter are given in Appendices. 7
