Field oriented control (FOC) of permanent magnet synchronous machine (PMSM)
TN111The Field-Oriented Control (FOC) method is a motor control strategy that orients the stator current vector in a rotating reference frame of the machine.
Proportional resonant controller
TN110A proportional resonant control can be seen as the implementation of PI controllers within a rotating reference frame (dq), which allows to re-locate the infinite DC gain at desired frequency.
Cascaded voltage control
TN108This note introduces the general operating principles of cascaded control and then details a possible design methodology. Then, an example of cascaded voltage control for a boost converter is provided.
Vector current control
TN106Vector current control is a widespread current control technique for three-phase AC currents, which uses a rotating reference frame, synchronized with the grid voltage (dq-frame)
PI controller implementation for current control
TN105This note introduces the general operating principles of a simple Proportional-Integral PI controller. An example of current control for a boost converter is provided, along with a practical control implementation.
SOGI PLL
TN104Second-order Generalized Integrators (SOGI) have recently been proposed for use as phase detectors for PLL implementations. These structures are essentially notch filters (band-pass) that can be easily tuned to the grid frequency.
