PMSM - Panels
Understanding the Panel
When starting the demo, the panel in figure 10 appears first with the default settings.
e
Figure 10: Start-Up Panel of the PMSM Drive Laboratory
The panel is to be operated as follows:
In the upper left corner, under DC Machine (DCM) the student can set the field and armature voltages of the DC machine and can change the value of the resistive load.
In the middle left corner, under Command, the student can select the type of control and transformation to be applied to the PMSM.
Under each command tab, there are control parameters and/or control buttons that are summarized in tables 2 and 3.
Once a control or a transformation is selected and applied, the student can observe the related waveforms under Oscilloscopes.
More details about the displayed waveforms are discussed later.
Table 2 summarized the control parameters, while table 3 is dedicated to the control buttons.
Control Parameters | Tab | Default Value | Interval of Variation |
|---|---|---|---|
DCM Field Voltage (V) | DC Machine | 0 | [0; 460] |
DCM Armature Voltage (V) | DC Machine | 0 | [0; 460] |
DCM Load Resistance (Ω) | DC Machine | 20 | [5; 35] |
Hysteresis Band | Current Control | 0.03 | [0.01; 0.2] |
Reference Current (A) | Current Control | 0 | [-18.2; 18.2] |
Reference speed (rpm) | Speed Control | 0 | [-1800; 1800] |
