This paper presents a discrete-time robust observer based control designed for magnetically levitated system (MLS). The MLS is an unstable system based on the method of transportation of moving an object using lift and propulsion provided by magnets. The nonlinear dynamics of MLS has been discretized using Euler's method. The proposed observer based control is designed using sliding mode approach with the super-twisting algorithm (STA). The stability analysis of overall system has been worked out with the help of Lyapunov theory. The simulation results are highlighted the robust performance of the proposed scheme in the presence of uncertainty.

In this study, first-order and second-order sliding mode speed controller for the Precision Modular Servo (PMS) setup produced by Feedback Instruments is proposed. The second-order sliding mode controller which permits decimate of the chattering phenomena is designed to control the real time speed of this electromechanical system. The Lyapunov stability theorem is used to confirm the stability of the system. And first-order and second-order sliding mode speed controllers are compared with each other. Experimental results are compared under condition of the same control strategy. The experimental results confirm that the offered super-twisting algorithm sliding mode controller eliminates the chattering while preserving the robustness of the control.

This article is concerned with observer-based fault estimation and adaptive fault tolerant control for a class of continuous-time dynamical systems. First, a second-order sliding mode observer is proposed, which is capable to eliminate chattering effects for fault estimation caused by the conventional sliding mode observer. Second, in order to avoid the cumbersome stability proving process by the geometric method, a Lyapunov function is adopted to prove the observer error dynamical system. Third, based on the estimated fault information by the proposed observer, an adaptive fault tolerant control law is developed to guarantee the stability of the faulty system. Finally, the proposed method is applied to the Boeing 747-100/200 flight control system, and the simulation results verify the effectiveness of the proposed scheme.

This paper is concerned with the problem of fault estimation for a class of Lipschitz nonlinear systems. In order to settle the chattering problem caused by traditional sliding mode observer for fault estimation, a second-order sliding mode observer is proposed on the basis of the super-twisting algorithm. Firstly, linear coordinate transformations are introduced to decouple the fault signal from the system. Secondly, the Lyapunov function approach is applied to derive the criteria guaranteeing the stability of the observer error dynamic system. The obtained results eliminate the cumbersome proving process for the stability of the super-twisting algorithm by the geometric method. Thirdly, an estimation of the fault is generated by the proposed second-order sliding mode observer. Furthermore, only the output information of the system and observer is necessary for fault estimation. Finally, a robotic arm system is employed to show the effectiveness of the proposed fault estimation method.

New variable gain super-twisting sliding mode observer for sensorless vector control of nonsinusoidal back-EMF PMSM

This paper presents a new discrete-time super-twisting sliding mode observer with variable gains for sensorless nonsinusoidal vector control of permanent magnet synchronous motors. This observer is adopted to estimate the back electromotive forces (back-EMF) that are required for the rotor speed estimation and for the nonsinusoidal vector control. In addition, their gains are time-varying to minimize the chattering. So, they are adjusted based on internal states of the super-twisting algorithm. The stability analysis is investigated from the Lyapunov theory for discrete-time systems. Finally, simulation and experimental results are presented to demonstrate the good performance and the effectiveness of the proposed observer. (C) 2016 Elsevier Ltd. All rights reserved.

Adaptive Fuzzy High-Order super-twisting Sliding Mode Controller for Uncertain Robotic Manipulator

引用

JOURNAL OF INTELLIGENT SYSTEMS 2017年第4期26卷 697-715页

作者： Goel, Ankur Swarup, Akhilesh Natl Inst Technol Kurukshetra Dept Elect Engn Kurukshetra Haryana India

This paper presents a novel adaptive fuzzy high-order super-twisting sliding mode controller, based on the modified super-twisting control (STC), to achieve accurate trajectory tracking for a robotic manipulator with unknown structured uncertainties, parametric uncertainties, and time-varying external disturbances. Initially, a non-linear homogeneous sliding manifold is designed to achieve finite-time convergence, better robustness, and good transient characteristics. Afterwards, conventional STC is modified with the new sliding surface that eliminates the limitation of STC application only on relative degree 1 systems. Moreover, two adaptive fuzzy systems are designed to replace the STC signals for handling the chattering problem and overestimating the controller gains. These fuzzy systems are continuously adjusted by two adaptation laws that are deduced from the Lyapunov stability theory. These adaptive laws need only a sliding surface variable as an input and generate the optimal controller gains as an output. The finite-time convergence and stability of the proposed controller is analyzed by the homogeneous Lyapunov stability theory. Finally, to show the efficacy of the proposed method, the controller is simulated on a 2-degree-of-freedom planar robotic manipulator to obtain the accurate trajectory tracking. Simulation results demonstrate the superiority of the proposed control scheme in the presence of structured and unstructured uncertainties.

Second Order Sliding Mode Control of DC-DC Converter used in the Photovoltaic System According an Adaptive MPPT

引用

INTERNATIONAL JOURNAL OF RENEWABLE ENERGY RESEARCH 2016年第2期6卷 375-383页

This paper deals with the development of an adaptive maximum power point tracking (MPPT) for Photovoltaic systems, whatever the type of the used converters (Buck, Boost, Buck-Boost). The main goal of the proposed work is to track the maximum power point (MPP) using adaptive algorithm (MPOA). This algorithm generates the output voltage reference Vref which must track the output voltage to reach the Maximum Power Point by modifying duty cycle of the DC-DC converter. In order to do that, second order sliding mode control is used. Furthermore, the use of the second order sliding mode control (SOSMC) can reduce the chattering phenomenon and ensure high transient response for a wide range of desired current or voltage under parameter variations. The proposed control is tested under different operating conditions. All results confirm the effectiveness of our proposed algorithm.
