Description

This block performs the control of up to 4 Resolvers and 4 Quadrature Encoders embedded in the machine model.

Mask Parameters

General tab

Block Mode: When selected Quad generic machine model, it controls 4 Resolver and 4 Quadrature Encoder blocks while when selected Dual PMSM Variable DQ it only controls 2 Resolver and 2 Quadrature Encoder blocks instead.

Resolver/Encoder Source Select: This parameter sets the resolver&encoder source.

Set all parameters from input ports: When selected, all other parameters will be disabled from the block mask and corresponding input ports will appear for dynamic access during the real-time simulation. Numerical value to send to the input port for the popup menus is written between square brackets in the description below.

Resolver Angle Offset: Offset apply to the rotor angle in degrees to adjust the phase of the resolver angle.

Resolver Pole Pairs: Number of pole pairs of the resolver emulator. This parameter should be an integer number between 0 and 128.

Resolver Reverse Speed: When selected [1], this option reverse the resolver sine/cosine modulation direction

Resolver Initial Angle: Offset apply to the rotor angle in degrees to adjust the starting phase of the resolver angle.

Resolver Carrier Select: This parameter selects the resolver carrier source, between the internal carrier generator [1] or an external source (generally from an analog input channel) [0].

Resolver Force Angle: When selected the rotor angle of the resolver stops rotating.

Resolver Carrier Frequency: Internal carrier generator frequency, in hertz.

Encoder Resolution: The quadrature encoder resolution, in pulses per revolution.

Encoder Polarity: This parameter sets the encoder polarity, Active-High [1] or Active-Low [0].

Encoder AleadsB: This parameter sets the BleadsA [1] or AleadsB [0].

Resolver External Carrier Shift: Offset apply to the delayed time of external resolver excitation, in second. Max value is 2.5e-6*2^10 = 0.00256s.

Encoder Angle Offset: Offset apply to the rotor angle in degrees to adjust the phase of the encoder angle.

Encoder Pole Pairs: Number of pole pairs of the encoder emulator. This parameter should be an integer number between 0 and 128.

Resolver Sine Modulator Sine Gain: The sine modulation output sine component amplitude. Default value is 1.

Resolver Sine Modulator Cosine Gain: The sine modulation output cosine component amplitude. Default value is 0.

Resolver Cosine Modulator Sine Gain: The cosine modulation output sine component amplitude. Default value is 0.

Resolver Cosine Modulator Cosine Gain: The cosine modulation output cosine component amplitude. Default value is 1.

Inputs

The input ports description is equivalent to the parameter description above.

Outputs

DataFrame: This output is a Simulink composite signal containing all outputs from the resolvers and encoders emulated by the block and should be connected to the loadin port of Generic Machine block.
