Lecture
This lecture covers the concept of negative feedback in tracking a trajectory, discussing the role of stimulus, noise, and perturbations in the environment, the components of a control system, and the process control involved in following a desired trajectory despite obstacles. It also presents a detailed example of the Falcon 9 rocket by SpaceX, explaining the various stages of its flight, including payload separation, flip maneuver, grid fins deployment, stage separation, boostback burn, entry burn, ascent, aerodynamic guidance, launch, and vertical landing. Additionally, it mentions the telemetry data and experimental landing attempts of the Falcon 9 rocket, as well as a similar example with SpaceShip SN8.
