Table 3 Comparisons between the Controllers
From: A survey on control issues in renewable energy integration and microgrid
Name of the controller | Advantages | Limitations |
|---|---|---|
Integral LQG controller | High band width as well as gain and phase margin | - |
PID controller | Low order transfer function matrices and easy to implement | Low band width |
Model predictive controller | Incorporate the constraint and less effected by noise | Lack of flexibility and high maintenance cost |
Damping controller | Low order transfer function matrices and no need to advanced digital signal processing | Critical need for a cost-effective control strategy |
