VOLTAGE ORIENTED CONTROL – SIMULATION

 With saturation and anti windup (Figure 3.22) We now include the back calculation anti windup and as we can see, the overshoot disappeared. The error is also reduce.

 With saturation, anti windup and active damping (APPENDIX B B.2, Figure 0.8, Table 0.1) In this simulation, the active damping doesn’t influence the system.

3.5.5 Simulation with current controller

The whole system can now be simulated. The rectifier is modeled according to the following Simulink scheme (Figure 3.23 and Figure 3.24) and data (Table 3.3)
