This work discusses the predefined performance tracking control issue of a vertical take-off and landing (VTOL) aircraft system. By using the designed control performance function, the constrained error signal of the aircraft system can be switched into an equivalent unconstrained signal. Moreover, fuzzy logic systems are introduced to cope with the aircraft system's unknown nonlinear dynamics. And then, adaptive fuzzy sliding control laws are designed by combining the fuzzy control method with the sliding mode control technique. Based on the designed control law, it is not only ensured that the outputs of the VTOL aircraft system can track the desired trajectories, but also that the tracking errors are constrained within a predefined range. Finally, the availability of proposed control method is testified through simulation example.
