Dr. Sandip Ghosh
My research focus is on developing controller design algorithms, mostly in LMI framework. With strong intention of bringing such control design methods to applications, we work also on wide-area control of power systems and structured control design for electrical machine drives, mostly in modern control framework.
Our group has been working on developing LMI based output feedback controller design (a classical problem in control theory) for past few years. We are looking ahead to develop new algorithms for LPV systems in coming years with applications to wind-energy systems. We are also working to extend our knowledge-base to multi-agent systems.
We have coined/introduced the following new concepts/methods to the research community so far.
1. Critical delay: The delay value(s) one should avoid in the feedback loop
2. Non-synchronized wide-area control: The wide-area damping control does not have a synchronization requirement
3. State-space framework for control design in machine drives: Demonstrated that the structured MIMO control design from robust control theory performs better, so far demonstrated for induction machine control, we are looking forward to extend it to other electrical machine drive applications, where multiple PI controller are to be designed
4. I-PD control: For integrating processes, I-PD controller is sufficient for full control of the process.
