in this paper a mesh-free model of the functionally graded material (fgm) plate is presented. the piezoelectric material as a sensor and actuator has been distributed on the top and bottom of the plate, respectively. the formulation of the problem is based on the classical laminated plate theory (clpt) and the principle of virtual displacements. moreover, the particle swarm optimization (pso) ...
this work proposes a neural-fuzzy sliding mode control scheme for a hydro-turbine speed governor system. considering the assumption of elastic water hammer, a nonlinear mode of the hydro-turbine governor system is established. by linearizing this mode, a sliding mode controller is designed. the linearized mode is subject to uncertainties. the uncertainties are generated in the process of linear...
The aim of this article is to develop new second-order fixed-time sliding mode controllers able tackle mismatched disturbances. Contrary what done in the literature, proposed sliding-mode control strategy does not use disturbance observers because surface possesses robustness properties. results are applied define a differentiator.
This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...
The design of integrated guidance and control system for flying objects is one of the research fields in the aerospace that is considered by researchers in recent years. Due to the nonlinearity of the kinematic and dynamic equations of the homing interceptors in the terminal phase and also existence of uncertainties such as target maneuvers, external disturbances and variations in aerodynamic c...
Permanent Magnet Synchronous Motor because of high energy storage capability is very important in electrical drive industry. Speed control of this motor suffers from parameter variations such as variable inductance. In this paper, The Integral-Terminal Sliding Mode Control (ITSMC) method is used to control the speed (torque) along with d-axis current control. This method is like to classic slid...
The advent of highly efficient and superior digital devices and fast microprocessors for control application has opened the field of discrete time controller design. This paper presents an exciting application of magnetic levitation system using discrete sliding mode control. There is a limited volume of literature available for discrete sliding mode control as applied to magnetic levitation sy...
This manuscript addresses trajectory tracking problem of autonomous underwater vehicles (AUVs) on the horizontal plane. Adaptive sliding mode control is employed in order to achieve a robust behavior against some uncertainty and ocean current disturbances, assuming that disturbance and its derivative are bounded by unknown boundary levels. The proposed approach is based on a dual layer adaptive...
