Description: 使用V/F原理的交流电机控制和简单的PWM算法
交流电机在连接到电源时只能以其额定速度运转，所以要改变转速必须改变电源频率。本篇应用文档展示了这些技术如何在AT90PWM3上简单的被实现，也说明了AVR RISC微处理器在电源控制方面的应用。-Induction motors can only run at their rated speed when they are connected to the main power supply. This is the reason why variable frequency drives are needed to vary the rotor speed of an induction motor. The aim of this application note is to show how these techniques can be easily implemented on a AT90PWM3, an AVR RISC based microcontroller dedicated to power control applications. Platform: |

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: Among many types of the
motors, three-phase induction machines still enjoy the same unparalleled
popularity as they did a century ago. At least 90 of industrial drive
systems employ induction motors.
Most of the motors are uncontrolled, but the share of adjustable speed
induction motor drives fed from power electronic converters is steadily
increasing, phasing out dc drives. It is estimated that more than 50 billion
dollars could be saved annually by replacing all "dumb" motors with
controlled ones. However, control of induction machines is a much more
challenging task than control of dc motors. Two major difficulties are
the necessity of providing adjustable-frequency voltage (dc motors are
controlled by adjusting the magnitude of supply voltage) and the nonlinearity
and complexity of analytical model of the motor, aggrandized by
parameter uncertainty.

Description: The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block. The motor drives a mechanical load characterized by inertia J, friction coeficient B, and load torque TL . The speed control loop uses a proportional-integral controller to produce the quadrature-axis current reference iq* which controls the motor torque. The motor flux is controlled by the direct-axis current reference id*. Block DQ-ABC is used to convert id* and iq* into current references ia*, ib*, and ic* for the current regulator. Current and Voltage Measurement blocks provide signals for visualization purpose. Motor current, speed, and torque signals are available at the output of the Asynchronous Machine block.-The induction motor is fed by a current-controlled PWM inverter which is built using a Universal Bridge block.
