Fractional-order proportional integral derivative (FOPID) controllers are becoming
increasingly popular for various industrial applications due to the advantages they can offer …

In this paper, an output feedback nonlinear control is proposed for a hydraulic system with
mismatched modeling uncertainties in which an extended state observer (ESO) and a …

This article studies the robust trajectory tracking control problem of a quadrotor unmanned
aerial vehicle (UAV). In order to guarantee the desired trajectory tracking performance in the …

The Fractional-order derivative (FOD) has a rich history in mathematical science. In
comparison, the half derivative has not been extensively used in applied science and …

Linear active disturbance-rejection control (LADRC) is investigated in this paper. First, it is
shown that LADRC structure can be changed to a two-degree-of-freedom (TDF) internal …

This paper proposes a practical adaptive fractional order (FO) terminal sliding mode control
(SMC) strategy for tracking control of the linear motor. Compared with conventional fast …

This paper presents the application of the Active Disturbance Rejection Control Technique
(ADRCT) to improve the performance of a Flywheel Energy Storage System (FESS). The …

Wind power plants have nonlinear dynamics and contain many uncertainties such as
unknown nonlinear disturbances and parameter uncertainties. Thus, it is a difficult task to …

This article presents a new method of designing the adaptive backstepping controller for
triangular fractional order systems with non-commensurate orders. The fractional order …

In this paper, we bring attention to the existence of fractional order Lyapunov stability
theorem which is strictly descripted by mathematic formulas. Firstly, we introduce fractional …
