Although there are several definitions and interpretations of the term morphing, it is generally understood that the concept can refer to both small-scale and large-scale shape …
Design of fault tolerant systems is a popular subject in flight control system design. In particular, adaptive control approach has been successful in recovering aircraft in a wide …
This work presents an adaptive control methodology that facilitates correct adaptation in the presence of actuator saturation constraints, model errors and initial condition errors. The …

This paper presents an improved Adaptive-Reinforcement Learning Control methodology to the problem of unmanned air vehicle morphing. Sequential Function Approximation, a …
MD Tandale, J Valasek - The Journal of the Astronautical Sciences, 2007 - Springer
Traditional adaptive control assumes full control authority and lacks an adequate theoretical treatment for control in the presence of actuator saturation limits. The adaptive dynamic …
