The software model is composed of two sections: the Simulink model and the TestDrive user interface. The Simulink model is used to design all the components that need to be simulated. All exercises included in this document are contained within one single Simulink model with the corresponding TestDrive User Interface. This user interface is used to interact with the system in real time.
Simulink Model
The screenshot of the Simulink model below shows an overview of the set of subsystems corresponding to each exercise detailed in the next chapter.
Test Drive User Interface
The TestDrive interface is composed of one main screen that offers of series of panels (OP8660, Ex1_ IGBT, Ex2_SyncGen, Scopes, and Scopes2), each one corresponding to an exercise. The main screen displayed depends on which panel is selected. When you first start TestDrive, the center screen is blank and you must select which panel to display.
The figure shown below is the basic panel.
OP8660 Panel
The OP8660 panel is divided into three sections.
| A | Panel selection buttons |
|---|---|
| B | OP8660 interface representation. Provides an interactive display of the OP8660 |
| C | The lower interface provides a series of tabs to adjust configurations |
Control Panel Section (A)
Displays the panels associated with the test bench:
| OP8660 | This is the main screen, displayed by default on startup. |
|---|---|
| Ex1_IGBT | This screen corresponds to Exercise 1. |
| Ex2_SyncGen | This screen corresponds to Exercise 2. |
| Scopes/Scopes2 | Both Scopes screens display oscilloscope results in the lower portion of the main screen. |
OP8660 Section Contents (B)
The contents of section B do not change (regardless of the tab displayed in the lower section):
| 6 Pulse inverter Outputs | Inverter output connectors send control pulses to the motor. |
|---|---|
| Encoder Inputs | Encoder input connectors read motor speed and position using differential ABZ encoder signals. |
| Analog Inputs | Analog input monitoring connectors for each channel (16). |
| Analog Outputs | Analog output monitoring connectors for each channel (16). |
| Digital Inputs | Digital input monitoring connectors for each channel (8). |
| Digital Outputs | Digital input monitoring connectors for each channel (8). |
| High Current Measurements | Probe connectors (max. 15A AC). Red and green LEDs indicate channel activity. |
| High Voltage Measurements | Probe connectors (max. 600 V). Red and green LEDs indicate channel activity. |
Configuration Section Tabs (C)
Interfaces to modify specific configurations and values through these five tabs:
| Inverter Control | For each of the two inverters, provides slides to increase or decrease the duty cycle from 0 to 1 on each of the inverter’s 3 phases, a knob and a slider to increase or decrease the PWM carrier frequency from 0 to 20,000. |
|---|---|
| Scopes | Oscilloscope display for each inverter. |
| Dyno Control | Scales to increase or decrease the dynamometer RPM Set Point and Maximum Torque and a button to Start/Stop. |
| Calibration Data | Gain and offset adjustment for the calibration of the current and voltage measurements. |
| Data Logging | Trigger/button to save measurements into a file and a file number. |
EX1_IGBT Panel
The EX1_IGBT panel button displays the panel used for Exercise 1. (Exercise 1 details are presented in a separate document, for training purposes).
EX2_SyNcGEN Panel
The EX2_SyncGen panel button displays the panel used for Exercise 2.
SCOPES Panel (1 & 2)
The Scopes panels allow you to view results on integrated oscilloscope screens.
