VOLTAGE ORIENTED CONTROL – SIMULATION
Figure 3.21 : Voltage control – With saturation15A
Figure 3.22 : Voltage control – With saturation15A and anti‐windup
Â Without saturation (Figure 3.20) We can see a fast response, a small error close to zero (0.0001V at 3second). But, we observe a very high current about 800A. We need to add the saturation here.
Â With saturation (Figure 3.21) The error has been increased lightly (Error 0.06V with Rload = 500Ω, Error 0.1V with Rload = 50Ω). We observe that the error depends on the saturation upper and lower value and depends also on the load. As the current is now limited the response is much slower. Finally, we also observe the so called integrator windup due to the saturation.
