Thanks to FOC it becomes possible to control, directly and separately, the torque and flux of AC machines. Field Orientated Controlled AC machines thus obtain every DC machine advantage: instantaneous control of the separate quantities allowing accurate transient and …

The FOC consists of controlling the stator currents represented by a vector. This control is based on projections that transform a three phase time and speed dependent system into a two coordinate (d and q coordinates) time invariant system.

This kind of optical distribution system is more convenient and can provide more possibilities to the future variations. Most of the rack mount ODF is 19”, which ensures that they can be perfectly installed on to the commonly used standard transmission rack.

The goal of the FOC (also called vector control) on synchronous and asynchronous machine is to be able to separately control the torque producing and magnetizing flux components.

FOC, also known as vector control, is an advanced motor control method to generate three-phase sinusoidal signals that can be controlled in frequency and amplitude in order to minimize the current, which means maximizing the power efficiency.

本资源文件包含了我个人在学习FOC（Field-Oriented Control，磁场定向控制）过程中整理的一些笔记。 这些笔记涵盖了FOC中的几大核心变换的数学推导，SVPWM（Space Vector Pulse Width Modulation，空间矢量脉宽调制）的详细过程，以及PID控制、积分抗饱和、磁链圆限制等关键算法的实现细节。 此外，还包括了基于多次谐波合成的马鞍波生成方法.

Jul 1, 2015 · The paper presents an improving speed control method using a field-oriented control (FOC) technique for the hysteresis current (HC) controller in the induction motor drive.

Optical distribution terminal box can be used in the connection and dispatch of outdoor optical fiber communication links, available for the connection of optical cable, optical fiber and patch cord, with the advantages of artistic appearance, convenient operation and long service life.

Field Oriented Control (FOC) is a well-known strategy for controlling diferent types of elec-trically commutated motors (e.g., Alternative Current based, Brushless DC, etc.) via phase-commutation.
