“…Commonly used observers mainly include sliding mode [13], [14] observer, disturbance observer, generalised proportional integral observer, extended state observer and so on. Wang et al [15] proposed an adaptive [16], [17] tracking controller based on disturbance observer, which solved the problem of uncertain disturbance in the dynamic model of thewheeled mobile robot and effectively improved the anti-interference ability of the control system. These disturbance observers mentioned above can be used to observe the system disturbance, and the appropriate observer can be selected according to the actual situation of the studied system.…”

The wheeled mobile robot is a typical uncertain robot system, which has typical nonholonomic characteristics and underdrive characteristics with different input and output dimensions. In the unknown environment, the slip and sideslip of the wheeled mobile robot are inevitable. Therefore, the research on trajectory tracking control of the wheeled mobile robot under sliding is of great significance. Aiming at the tracking problem of the wheeled mobile robot system with side slip disturbance, a Lyapunov design method based on extended state observer is proposed by using active disturbance rejection strategy. The influence of the sideslip disturbance on the system is regarded as the total disturbance of the system, and the extended state observer is used to observe the total disturbance in real time. The observation of the total disturbance by the extended state observer plays a patch role in the control law. When there is no disturbance, the system returns to the Lyapunov control under the nominal model. When there is a disturbance, the disturbance is compensated by the extended state observer, so that the system is approximately equivalent to the nominal model without being affected by the disturbance. The simulation results show that the system has better transient performance and anti-interference performance compared with the inverse control regardless of whether it is disturbed or not.

“…However, the unknown input observer-based active fault-tolerant control for induction machine is developed in [18], which can make system outputs to track their desired reference signal in finite time, and the closed-loop stability is established based on the Lyapunov function [19]. Also, the observer-based fuzzy fixed time terminal sliding mode controller is proposed in [20] for a nonlinear dynamic of vehicle model, where the convergence of tracking error to zero achieves in finite time [21]. Furthermore, an experimental study on a nonlinear observer application for a flexible parallel robot is presented in [22].…”

This paper is concerned with the fast state observer for a class of continuous-time linear systems with unknown bounded parameters and sufficiently slowly time varying which satisfy the usual assumptions of conventional state observer for time-invariant plants. A less conservative approach based on hyperstability analysis is proposed to deal with the tracking error involved in Popov’s inequality. Sufficient conditions that ensure the asymptotic stability of the closed-loop system are established and formulated in term of a nonlinear part which is designed with appropriate proportional and derivative gains. This observer included the derivative of the estimation error. The results obtained are satisfactory and less conservative than the Lyapunov stability analysis for the estimation error dynamic system. Also, it is showed that with a good choice of Proportional-Derivative (PD) gains, it is possible to reduce in this case to zero, the estimation error on the one hand, and on the other hand to reduce it to small residues in an asymptotic way. Finally, a numerical example of a lateral motion of CESSNA 182 aircraft system is presented to reconstruct the sideslip angle and the roll angle, respectively, and to highlight the efficiency of the approach that has been developed.
