“…The concept of non-integer differentiation was developed far in the past and was recognized in the mathematics research community. Many definitions and approximations were initiated meanwhile, and we should recall here the most popular ones, due to Riemann-Liouville (R-L) and Grunwald-Letnikov (G-L) [11].The R-L defintion of fractional order integral is given by: ISSN: 2302-9285  Automatic voltage regulator performance enhancement using a fractional order model … (Imen Deghboud)…”

In this paper, a new design method for fractional order model predictive control (FO-MPC) is introduced. The proposed FO-MPC is synthesized for the class of linear time invariant system and applied for the control of an automatic voltage regulator (AVR). The main contribution is to use a fractional order system as prediction model, whereas the plant model is considered as an integer order one. The fractional order model is implemented using the singularity function approach. A comparative study is given with the classical MPC scheme. Numerical simulation results on the controlled AVR performances show the efficiency and the superiority of the fractional order MPC.

“…Similarly to fault detection approaches, the sliding mode technique has been the most popular approach among researchers in conceiving reliable fractional fault tolerant control strategies, since this approach possess attractive features in terms of reducing the chattering during the sliding phase and smoother control efforts [58]. These works include [59,60,61,62,63,64,65,66,67,68], additionally other fractional sliding mode structures have also been studied such as Terminal sliding mode control [69,51] and nonsingular terminal sliding mode [32,70].…”

“…Since then, fractional calculus has been introduced in several control schemes and methods such as sliding mode control [14], predictive control [15,16], and particularly adaptive control [17,18,19]. Recently, many research works have proposed Fault Tolerant Controllers using fractional order models in order to improve the efficiency and performance of the controlled plants [20,21].…”

In this paper, a comprehensive review of recent advances and trends regarding Fractional Order Fault Tolerant Control (FOFTC) design is presented. This novel robust control approach has been emerging in the last decade and is still gathering great research efforts mainly because of its promising results and outcomes. The purpose of this study is to provide a useful overview for researchers interested in developing this interesting solution for plants that are subject to faults and disturbances with an obligation for a maintained performance level. Throughout the paper, the various works related to FOFTC in literature are categorized first by considering their research objective between fault detection with diagnosis and fault tolerance with accommodation, and second by considering the nature of the studied plants depending on whether they are modelized by integer order or fractional order models. One of the main drawbacks of these approaches lies in the increase in complexity associated with introducing the fractional operators, their approximation and especially during the stability analysis. A discussion on the main disadvantages and challenges that face this novel fractional order robust control research field is given in conjunction with motivations for its future development. This study provides a simulation example for the application of a FOFTC against actuator faults in a Boeing 747 civil transport aircraft is provided to illustrate the efficiency of such robust control strategies.

This paper is to proposes a fractional order adaptive control scheme design for actuator failure compensation in order to balance of a ball-beam system with redundant actuators. The proposed controller is based on a fractional order sliding surface from which an adaptive actuator failure compensation control scheme is obtained. In order to control the dual ball-beam system with redundant motors, a linearized model is derived, which is subjected to actuator failures. A set of numerical simulation tests representing few selected types of actuator failures scenarios are carried out to assess the output tracking performance of the proposed controller design when dealing with such failures
