Fractional order sliding-mode control for permanent magnet synchronous motor. Control Theory & Applications, 2012, 29(9): 1193-1197 (张碧陶, 皮佑国. 基于分数阶滑模控制技术的永磁同步电机控制. 控制理论与应用, 2012, 29(9): 1193-1197)ZHANG Bitao, PI Youguo.Fractional order sliding-mode control ...
To deal with the chattering phenomenon existing in conventional integral order sliding-mode controller, we proposed a fractional order sliding-mode controller and apply to control the permanent magnet synchronous motor (PMSM). The soft-switching will not directly act on the sliding-mode surface or on...
Since the Leibniz rule for integer-order derivatives of the product of functions, which includes a finite number of terms, is not true for fractional-order (FO) derivatives of that, all sliding mode control (SMC) methods introduced in the literature involved a very limited class of FO nonlinea...
Water level regulation of irrigation canals represents a major challenge for control systems design. Those systems exhibit large dynamic variations in their operating conditions. To overcome this fact, robust controllers should be applied. The sliding mode control paradigm reveals this ability which make...
This article proposes a novel fractional order sliding mode control for a class of fractional order and integer order systems with mismatched disturbances. First, a new fractional order disturbance observer is designed to estimate the fractional order differential of the mismatched disturbance directly. ...

Introduction The electric vehicle sector has experienced substantial growth in recent years, largely attributed to the implementation of the “dual-carbon” target pro...
Sliding mode control, due to its robustness to parameter uncertainty and external disturbance, is a common robust control method. In sliding mode control, one of the most important steps in controller design procedure is to find the proper bounds of uncertainties. Also, when the first order slidi...
