RTE-Drive Machines

Block

Note: This block is obsolete.

Description

This block computes the phase domain time-varying inductance matrix of a permanent magnet synchronous machine corresponding to the Ld Lq Park transform inductances and rotor angle.

Mask

RTE-Drive Phase Domain PMSM Inductance Mask

Parameters

Voltage base [V]	The model base voltage.
Current base [A]	The model base current.
Electric frequency base [Hz]	The model base frequency. Note that the base choice must be the same as in the RTE-Drive Phase Domain PMSM block.
Number of Pair of Poles	The machine number of pole pair.
Sample Time [s]	The model sample time.

Input

Lq [H]	Q-axis inductance in the Park referential.
Ld [H]	D-axis inductance in the Park referential.
SinCos	The sine and cosine of the rotor electric angle.

Note: The Ld and Lq value correspond to the Krause Park transformation in which, for positive speed, the q-axis is ahead of the d-axis and the Park transform has 2/3 factor and all positive sign (no negative row).

Output

Lx [pu]	Inverse of the reduced inductance matrix [2x2], which is time-varying.

Characteristics

Direct Feedthrough	Yes
Sample Time	Inherited and fixed discrete.
Work Offline	Yes
Dimensionalized	No

Example

None.
