Stator flux oriented control
WebMay 9, 2024 · It is well known from vector control that orienting the machine model presented in Section 3 in the stator flux reference frame is an effective way for decoupling active power (or torque) and reactive power control by means of rotor current regulation. WebFOC is a control scheme in which a d-q coordinates reference frame that is locked to the motor flux space vector is used to achieve decoupling between the motor flux and torque. Consequently, they can be separately controlled by stator direct-axis and quadrature-axis currents, respectively.

WebStator flux oriented control of a cascaded doubly-fed induction machine. A cascaded doubly-fed induction machine (CDFM) is a connection of two wound rotor induction machines. In comparison to a single doubly-fed induction machine (SDFM) brushes are obsolete. Due to recent developments in brushless doubly-fed machine design, there is a … WebDec 1, 2024 · This thesis proposes an alternative FOC scheme using stator flux as a reference for our rotating coordinate system (f, t), hence, called stator flux-based field-oriented control (SFOC).
Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector. One component defines the magnetic flux of the motor, the other the torque. The control system of the drive calculates the corresponding current component references from the flux and torque references … Webpopular with the sensorless Field Oriented Control (FOC) technique in industrial and automotive systems because of high power density, high efficiency and fast dynamic performance. ... In brief, the goal of FOC is to align the stator flux to 90° of the rotor flux, that is, orthogonal to the rotor flux. To do this, a three-phase stator current ...
WebJan 4, 2012 · Field Oriented Control (FOC): Also known as vector control, FOC provides better efficiency at higher speeds than sinusoidal control. ... In FOC, the stator currents are measured and adjusted so that the angle between the rotor and stator flux is 90 degrees to achieve the maximum torque (as shown in the following figures) ... WebBased on the virtual stator-PM-flux-oriented control, the operating performance of the AFSFPM machine was studied in the entire speed operating region. It can be concluded that the MTPA strategy takes advantage of the reluctance torque and maximizes the load capability and the MOP flux-weakening strategy broadens the operating range of constant ...
WebField-Oriented Control (FOC), also known as vector control, is a technique used to control Permanent Magnet Synchronous Motor (PMSM) and AC induction motors (ACIM). FOC provides good control capability over the full torque and speed ranges. The FOC implementation requires transformation of stator currents from the stationary reference …
