TF/TA^2 trajectory tracking using nonlinear predictive control approach

摘要

The use of a methodology of nonlinear continuous predictive control to design the guidance control law for the aircraft TF/TA^2 trajectory tracking problem is emplojed. For the derivation of the predictive control law, by using Taylor series expansion, and based on optimizing a performance index which is a quadratic function of both the predictive value of the state variables and the control inputs, a state variable feedback controller for nonlinear systems is obtained, and it provides a tradeoff between satisfactory tracking performance and the control magnitude requirements. Numerical simulation results for a supersonic fighter aircraft model show the viability of this approach.
