Discrete-Time Sliding-Mode Control Based on Neural Networks

In this paper, we present a new sliding mode controller for a class of unknown nonlinear discrete-time systems. We make the following two modifications: 1) The neural identifier which is used to estimate the unknown nonlinear system, applies new learning algorithms. The stability and non-zero properties are proved by dead-zone and projection technique. 2) We propose a new sliding surface and gi...

Optical Frequency Synthesis Based on Mode-Locked Lasers

The synthesis of optical frequencies from the primary cesium microwave standard has traditionally been a difficult problem due to the large disparity in frequency. Recently this field has been dramatically advanced by the introduction and use of mode-locked lasers. This application of mode-locked lasers has been particularly aided by the ability to generate mode-locked spectra that span an octa...

Self-tuning Control Based on Discrete Sliding Mode

This paper presents a multivariable self-tuning control based on the idea of discrete-time sliding mode. The previous stability proof based on the Lyapunov function is corrected in the MIMO framework that plant input and output have the same dimension. The performance of the proposed method is evaluated in the simulation environment designed for MBD (model based development) of automotive syste...

Discrete-time Sliding-mode Wmr Control Based on Parameter Identification

In this paper a discrete-time adaptive sliding mode controller for wheeled mobile robots (WMR) is presented. The dynamical model with time-varying mass has been taken into account. The sliding-mode controller has designed on two components, corresponding to angular and position motion, respectively. In order to accomplish the robustness against parameter uncertainties (robot mass and moment of ...
