Sliding mode control revisited
Transactions of the Institute of Measurement and Control, 2020Controller design for nonlinear systems in its general form is complicated and an open problem. Finding a solution to this problem becomes more complicated when unwanted terms, such as disturbance, are taken into account. To provide a robust design for a subclass of nonlinear systems, sliding mode controllers (SMCs) are used.

Approximability of Sliding Modes and Regularization
International Workshop on Variable Structure Systems, 2006. VSS'06., 2006Approximability of sliding motions for control systems governed by nonlinear finite-dimensional differential equations is considered. This regularity property is shown to be equivalent to Tikhonov well-posedness of a related minimisation problem in the context of relaxed controls.

2016 American Control Conference (ACC), 2016
This paper presents a design method for controlling multiple sliding surfaces of nonlinear systems with matched uncertainty using a single actuator. Sliding mode control, in general, requires one actuator for every control objective. Compared to the vast literature on sliding mode control, there has been little work on general theories that can be ...

Sliding mode functional observers
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008In this paper the concept of sliding mode is introduced in the design of functional observers. Conditions for the existence of the observer are given. How to design the observer parameters are also shown. Under special circumstances the sliding mode functional observer proposed in this paper reduces to the Utkin state observer.

Design of Sliding Mode Indicator
2007 American Control Conference, 2007A scheme of the sliding mode (SM) indicator to detect the boundary existence of the sliding mode for a thermal control system is proposed. The derived sliding mode control algorithm is supposed improve the control performance of such an important characteristic of the system as the thermal field of the oven.

Sliding Empirical Mode Decomposition
The 2010 International Joint Conference on Neural Networks (IJCNN), 2010Biomedical signals are in general non-linear and non-stationary which renders them difficult to analyze with classical time series analysis techniques. Empirical Mode Decomposition (EMD) in conjunction with a Hilbert spectral transform, together called Hilbert-Huang Transform, is ideally suited to extract informative components which are characteristic

Sliding Mode Servomechanism Design
2006 IEEE International Conference on Control Applications, 2006In this paper, a frequency-shaped optimal sliding mode approach combined with Lyapunov based backstepping design is presented to solve the robust servomechanism problem. The parametric uncertainties, unmodeled dynamics and uncertain exogenous disturbance belonging to a specified class are attenuated by using compensator dynamics introduced in sliding ...

IEEE Transactions on Automatic Control, 2001
Summary: This paper studies sliding-mode control where the usual regularity assumptions need not hold. In particular, we allow ``singular submanifolds'' near which the state trajectory cannot be steered toward the sliding surface. For nonlinear systems whose singular submanifold satisfies suitable transversality conditions, we identify a class of ...

Sliding-mode repetitive learning control with integral sliding-mode perturbation compensation
ISA Transactions, 2009This paper proposes a sliding-mode repetitive learning control (SMRLC) scheme with an integral sliding-mode perturbation observer (ISMPO) for repetitive tracking control tasks. The three control strategies which are synthesized to yield excellent tracking performance are: (1) the pole-placement feedback control to specify the desired error dynamics; (2)
