The article proposes a new robust tracking control method for UAV systems in roll and pitch angular planes. The main achievement of the obtained controller is a guarantee that the output signal is confined in a sufficiently small prespecified bounded set formed by arbitrary continuously differentiable functions. The method is applied to a multiple-input multiple-output quadrotor model under external bounded disturbances and parametrical uncertainties influence. Results and achieved performance are verified via representative computer simulation results.

In this paper, we present a finite time convergence (FTC) parameter estimator for a class of non-linear MIMO systems. The designed FTC estimator is based on a continuous-time parameter identification algorithm that was recently proposed by the authors. Compared to the previous solution the new modified estimator doesn’t require the unobvious to achieve in practice assumptions imposed on regression functions to ensure guaranteed convergence. As a practical example, we use a “Twin Rotor MIMO System” laboratory bench which model is given by a nonlinear multi-channel system with cross-couplings. Significant improvement of the transient behavior for the new parameter estimator is demonstrated via representative simulation results.
