CONTROL SYSTEMS THEORY APPLIED TO THE RE-ENTRY OF AEROSPACE VEHICLES, I.
Abstract
In an effort to bridge the gap between theory and practice the re-entry problem area is chosen to apply advanced control techniques. This problem area affords many separate areas where theory could be applied. First of all, Pontryagin's 'Maximum Principle' is applied (short of numerical computation) to formulate the determination of optimal trajectories which minimizes heating and deceleration. Secondly, optimization methods are used as a possible solution to the flight-path control problem. Several alternative procedures are provided. Next, some considerations are given to control loops inside of the flight-path control loop (attitude control problem). Lastly, the re-entry problem provides an area where the so-called 'adaptive control' concepts are applicable. A method is provided where the on-line controller with bounds on the controls can be attacked. Identification procedures are also provided. A bibliography is compiled for the area of re-entry of aerospace vehicles. (Author)
