In this paper, a new discontinuous control strategy is proposed for robust stabilization of a class of uncertain multivariable linear time-delay system with delays in both the state and control variables. The integral sliding mode control technique is applied to compensate the uncertainty term and then a predictor is used to obtain free-delay closed-loop system with desired spectra. For systems...

: The input chattering in the sliding mode control (SMC) is alleviated through a low pass filter. When the low pass filter is added to the original system, the overall system including the low pass filter dynamics can not satisfy the matching condition. So the integral SMC is applied for a main controller. A sliding surfaces are designed carefully to make the overall dynamics same with the nomi...

The problem of the realization of integral sliding mode controllers based only on output information is discussed. The implementation of an output integral sliding mode controller ensures insensitivity of the state trajectory with respect to the matched uncertainties from the initial time moment. In the case when the number of inputs is more than or equal to the number of outputs, the closed lo...

An Integral Sliding Mode approach to hierarchical control of interconnected systems with uncertainties arising from unknown interconnection states and unknown parametric variation is proposed. The work is based on a recent study using constrained LQR showing that a two-level hierarchical control system with on-line learning coordination provides a suitable architecture for control of uncertain ...

This paper deals with the practical robust stabilization and tracking problems of the perturbed multidimensional Heisenberg system with some additional integrators in the control input path. This objective is achieved by the use of variable structure control laws with an integral augmented sliding variable. This note shows how to select the integral sliding surface in such a way that the practi...

This paper presents a particle swarm optimization (PSO)-based neuro-sliding mode controller for the transient stability enhancement of multimachine power systems with unified power flow controller (UPFC). The UPFC is modeled as controllable loads. These controllable parameters are obtained using the sliding mode control (SMC) strategy. A PSO-based single neuron controller is used to adapt the p...

A multi-input-multi-output (MIMO) sliding mode control scheme was developed with guaranteed stability to simultaneously control air-to-fuel ratio (AFR) and fuel ratios to desired levels under various air flow disturbances by regulating the mass flow rates of engine port-fuel-injection (PFI) and direct injection (DI) systems. The sliding mode control performance was compared with a baseline mult...

A new tuning method for active vibration absorber design is presented in this paper. A robust, adaptive control scheme based on a variable structure with an adaptive discontinuity surface is designed and simulated. Robust synthesis of an adaptive discontinuity surface based on an augmented state-space is discussed. The proposed tuning scheme has three superior features compared with the existin...

This paper describes the design of a novel sliding mode controller for tracking of robotic manipulators. By using a proportional-integral combination of the sliding function in the boundary layer, control chattering is eliminated without deterioration of system robustness. Theoretical developments are verified by simulation results for the tracking problem of a 2 DOF robotic manipulator.
