* What is a PID Controller? Significance of each of its components. How would the system behave if PID was used when not needed? * Spool of String physics puzzle * Change in velocity with respect to time when a body goes downhill and climbs uphill. * Feed-forward Control design advantage * Root Locus significance. How do you arrive at Stability criteria based on Root Locus? * Application of Kalman filters in Control Engineering * Water Level Control: What would be your approach to design a controller for this system. They go on improvising the cases and add limitations. You are expected to optimize your approach each time
