Abstract:

This paper presents a new stabilizing control law for a planar vertical take-off and landing aircraft. The model is first transformed into an equivalent form, and then a control law consisting of a linear term and a saturated term is given for a related subsystem, with the saturation levels being assigned as large as possible. Compared to the existing saturation scheme in which all states are restricted by saturations, the design brings about a relatively fast convergence. The effectiveness and advantage of the design are validated by numerical simulations.
