The block implements a logical algorithm for selecting the inverter keys depending on the position of the rotor and the sign of the specified torque.
How the output signals of the block and the keys of the three-phase inverter is matching each other, is illustrated in the figure (Figure 1).
Рисунок 1. Distribution of output signals
Key selection signals are generated by the model depending on the value of the “sign” signal and signals from the RPS in accordance with the table (Table 1).
| Field angle | 0...30° | 30°...90° | 90°...150° | 150°...210° | 210°...270° | 270°...330° | 330°...0 |
|---|---|---|---|---|---|---|---|
| RPS (3 2 1) | 0 0 1 | 0 1 1 | 0 1 0 | 1 1 0 | 1 0 0 | 1 0 1 | 0 0 1 |
| sign = 0 (M > 0) |
- | S2 | S2 | - | S1 | S1 | - |
| S3 | S3 | - | S4 | S4 | - | S3 | |
| S6 | - | S5 | S5 | - | S6 | S6 | |
| sign = 1 (M < 0) |
- | S1 | S1 | - | S2 | S2 | - |
| S4 | S4 | - | S3 | S3 | - | S4 | |
| S5 | - | S6 | S6 | - | S5 | S5 |
