Methods

Class methods are listed below. Inherited methods are not included.

.SynEquivalentCircuit/SynEquivalentCircuit is a constructor.

this = SynEquivalentCircuit(R, Phi, LM, p, varargin) Documentation for SynEquivalentCircuit/SynEquivalentCircuit doc SynEquivalentCircuit

.SynEquivalentCircuit/constant_voltage_vector is a function.

phi = constant_voltage_vector(this, n)

.SynEquivalentCircuit/current_from_voltage is a function.

i = current_from_voltage(this, n, ud, uq)

.from_model Instantiate equivalent circuit for model.

circuit = from_model(model)

Initialize using default settings (see below).

circuit = from_model(model, key1, val1, …)

Initialize with any of the following key-value pairs:

  • ‘idq’, idq : compute parameters at the specified (id,iq) point. Default [0;0].

  • ‘mode’ : either modes supported by compute_inductances_static_averaging (defaults to ‘differential’) OR ‘simplified’

  • ‘angle’, angle : Vector of electrical angles (rad) to average eq. circuit parameters over. Default linspace(0, 2*pi/6, 30).

  • Any key-value pair of compute_inductances_static_averaging (default mode: differential)

  • Any key-value pair of SynEquivalentCircuit

** NOTE In case the equivalent circuit is used to compute supply parameters (id, iq) or (Ud, Uq) for a delta-connected machine, it seems that the 'transform_to_star', false argument pair is needed. Verifying the correct behaviour manually is highly recommended.

.get_max_torque Compute maximum attainable torque.
