ISRO: (jointly with Prof. Madhu Belur). Title: Hybrid Control and Fault Detection during re-entry of Reusable Launch Vehicles, 2009-2012: This project considers the problem of controlling a Reusable Launch Vehicle (RLV) during re-entry into the earth’s atmosphere. The objective is to find a systematic solution to the interdependent problems of designing a control law, detecting the set of functioning control effectors at any instant, and allocating the required control torque to these effectors in a reconfigurable manner.

Department of Science and Technology: (jointly with Prof. Subhananda Chakrabarti) Title: CONTROL AND OPTIMIZATION OF PULSED LASER DEPOSITION TECHNIQUE FOR GROWTH OF ZnO BASED MATERIALS AND DEVICES, 2009-2012: The problem of modeling and control of the pulsed laser deposition (PLD) process for growth of p-doped ZnO based materials is considered. The principal objectives are to develop and experimentally verify an analytical/numerical model for the PLD process, which will then be used to identify, predict and optimally control the various critical parameters in an experimental setup.
