In course

ME-323: Chemical process control

Provide the students with basic notions and tools for the modeling and analysis of dynamic systems. Show them how to design controllers and analyze the performance of controlled systems. ...

Description

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.

Falcon 9 first-stage landing tests

The Falcon 9 first-stage landing tests were a series of controlled-descent flight tests conducted by SpaceX between 2013 and 2016. Since 2017, the first stage of Falcon 9 missions has been routinely landed if the rocket performance allowed it, and if SpaceX chose to recover the stage. The program's objective was to reliably execute controlled re-entry, descent and landing (EDL) of the Falcon 9 first stage into Earth's atmosphere after the stage completes the boost phase of an orbital spaceflight.

Falcon 9 flight 20

Falcon 9 flight 20 (also known as Orbcomm OG2 M2) was a Falcon 9 space launch that occurred on 22 December 2015 at 01:29:00 UTC (21 December, 8:29:00 pm local time). It was the first time that the first stage of an orbital rocket made a successful return and vertical landing. The successful landing of the first stage at Landing Zone 1, near the launch site, was the result of a five-year technology development program to develop a reusable launch system and came on a flight test that followed the primary launch mission.

Falcon 9 Full Thrust

Falcon 9 Full Thrust (also known as Falcon 9 v1.2, with variants Block 1 to Block 5) is a partially reusable medium-lift launch vehicle, designed and manufactured by SpaceX. Designed in 2014–2015, Falcon 9 Full Thrust began launch operations in December 2015. As of , Falcon 9 Full Thrust had performed launches without any failures. Based on the Lewis point estimate of reliability, this rocket is the most reliable orbital launch vehicle currently in operation.

Falcon Heavy

Falcon Heavy is a partially reusable super heavy-lift launch vehicle that can carry cargo into Earth orbit, and beyond. It is designed, manufactured and launched by American aerospace company SpaceX. The rocket consists of a center core on which two Falcon 9 boosters are attached, and a second stage on top of the center core. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System, and the fourth-highest capacity of any rocket to reach orbit, trailing behind the SLS, Energia and the Saturn V.

SpaceX

Space Exploration Technologies Corp., doing business as SpaceX, is an American spacecraft manufacturer, launch service provider and satellite communications company headquartered in Hawthorne, California. The company was founded in 2002 by Elon Musk with the goal of reducing space transportation costs and to colonize Mars. The company manufactures the Falcon 9, Falcon Heavy and Starship heavy-lift launch vehicles, the Cargo Dragon and Crew Dragon spacecraft, the Starlink mega-constellation satellite and rocket engines.
