Hybrid Optimal Control Approach to Commercial Aircraft Trajectory Planning

Back
Abstract:
Given the sequence of phases and flight modes conforming the flight profile of a commercial aircraft, the initial and final states and a set of path constraints, the problem of finding control inputs, switching times between flight modes and the corresponding trajectory of the aircraft that minimizes fuel consumption is solved. The aircraft in flight is modelled as a hybrid dynamical system, i.e., a system that has a continuous and a discrete dynamics, where the distinct discrete dynamics corresponds to different flight phases and switches between them occur either in response to control law or when the state of the system reaches prescribed regions of the state space. The motion of the aircraft is described by a point variable-mass dynamic model. The hybrid optimal control problem is converted into a conventional optimal control problem making the unknown switching instants part of the states. The resulting problem is then solved solved using a collocation method. Results show that current flight profiles efficiency could be substantially improved.
