SUMMARY:Control of a Hypersonic Vehicle with Actuation Bounds and Scramjet 
 Engine Constraints

 ic vehicles (AHVs) have the potential to revolutionize space access and hi
 gh-speed global transportation. These vehicles can cruise at Mach 5 and ab
 ove\, making them highly attractive for many time-critical applications. F
 urthermore\, by using atmospheric oxygen\, they eliminate the need to carr
 y oxidizers. Consequently\, AHVs offer increased payload capacities\, reus
 ability\, and reduced construction and operational costs.\nThis work addre
 sses the tracking control problem for a generic AHV subject to realistic s
 tate-dependent constraints imposed by its propulsion system. Typical AHV d
 esigns have highly unstable dynamics\, strong aeropropulsive couplings\, a
 nd significant uncertainties. These intricate dynamics are captured by the
  Technion’s Scramjet-powered Air Breathing Aerospace Research model of a
  Hypersonic Vehicle (TSABAR-HV)\, which is used as a physical baseline. Fr
 om a control perspective\, these characteristics and constraints pose cons
 iderable challenges that must be addressed to develop a functional AHV.\nT
 he controller is designed for a mathematically tractable control-oriented 
 model which is derived from the detailed TSABAR-HV truth model. Tracking p
 erformance is guaranteed through a control Lyapunov function (CLF). Within
  this framework\, a control input for tracking is computed by solving a qu
 adratic program (QP) that enforces the CLF condition. This yields an optim
 al\, nominal pointwise min-norm (PMN) controller. To ensure that the syste
 m does not violate its constraints\, this nominal input is minimally augme
 nted via another PMN solution derived from a high-order barrier Lyapunov f
 unction (BLF). The CLF and BLF are made robust to uncertainties by assumin
 g that they can be bounded. This bound is used to formulate conservative r
 equirements of the CLF and BLF. Numerical simulations demonstrate that the
  proposed controller successfully tracks reference signals while strictly 
 adhering to state constraints.\nThis work is towards an M.Sc. degree under
  the supervision of Assoc. Prof. Moshe Idan\, The Stephen B. Klein Faculty
  of Aerospace Engineering\, Technion.\n Details: \n
