Description: This book is intended to be an exposition of the modeling and control of
electric machines, specifically, the direct current (DC) machine and the
alternating current (AC) machines consisting of the induction motor, the
permanent magnet (PM) synchronous motor, and the brushless DC motor.
The particular emphasis here is on techniques used for high-performance
applications, that is, applications that require both rapid and precise control
of position, speed, and/or torque. Traditionally, DC motors were reserved
for high-performance applications (positioning systems, rolling mills,
traction drives, etc.) because of their relative ease of control compared to
AC machines. However, with the advances in control methods, computing
capability, and power electronics, AC motors continue to replace DC motors
in high-performance applications. The intent here is to carefully derive
the mathematical models of the AC machines and show how these mathematical
models are used to design control algorithms Platform: |

Description: This paper presents the Direct Power Control of
Three-Phase Matrix Converters (DPC-MC) operating as Unified
Power Flow Controllers (UPFC). Since matrix converters allow
direct AC/AC power conversion without intermediate energy
storage link, the resulting UPFC has reduced volume and cost,
together with higher reliability. Theoretical principles of DPCMC
method are established based on an UPFC model, together
with a new direct power control approach based on sliding mode
control techniques. As a result, active and reactive power can be
directly controlled by selection of an appropriate switching state
of matrix converter. This new direct power control approach
associated to matrix converters technology guarantees
decoupled active and reactive power control, zero error
tracking, fast response times and timely control actions.
Simulation results show good performance of the proposed
system. Platform: |

研究得到广泛关注。特别是 20 世纪 80 年代直接转矩控制（DTC）的出现，以其简洁高

关频率。大功率场合下必须低开关损耗和良好转矩控制性能，传统 DTC 难以同时满足
需求。
-With the beginning of the AC induction motor speed control field dominance, speed control system for high-performance induction motor research has been widespread concern. Especially in the 1980s, Direct Torque Control (DTC) appeared, with its simple and efficient way to control and further improve the performance of asynchronous motor. However, the existence of traditional DTC will produce torque and torque ripple flux hysteresis width when making steady. Therefore, high-performance control requires a narrower hysteresis width, corresponding demanding inverter switching frequency. Where high power must be low switching losses and good torque control performance is difficult to meet the needs of traditional DTC. Platform: |
