Disturbance observer (DOB) has been one of the most widely used robust control tools since
it was proposed by Ohnishi in 1983. This paper introduces the origins of DOB and presents …

Due to its abilities to compensate disturbances and uncertainties, disturbance observer
based control (DOBC) is regarded as one of the most promising approaches for disturbance …

A new approach to the design of nonlinear disturbance observers (DOBs) for a class of
nonlinear systems described by input-output differential equations is presented in this paper …

In this paper, a dynamic surface control (DSC) scheme is proposed for a class of uncertain
strict-feedback nonlinear systems in the presence of input saturation and unknown external …

The problem of anti-disturbance control has been an eternal topic along with the
development of the control theory. However, most methodologies can only deal with systems …

Considering the variations of inertia in real applications, an adaptive control scheme for the
permanent-magnet synchronous motor speed-regulation system is proposed in this paper …

A concise, in-depth introduction to active disturbance rejection control theory for nonlinear
systems, with numerical simulations and clearly worked out equations Provides the …

The work presented here is concerned with the robust flight control problem for the
longitudinal dynamics of a generic airbreathing hypersonic vehicles (AHVs) under …

This paper addresses the prediction accuracy enhancement problem in the context of
continuous-time model predictive control (MPC) by using a disturbance observer. The …

A new continuous dynamic sliding-mode control (CDSMC) method is proposed for high-
