Terminal Sliding Mode Control for Nonlinear Systems with both Matched and Unmatched Uncertainties
In this paper, we extend the sliding mode idea to a class of unmatched uncertain variable structure systems. This method is achieved with introducing a new terminal sliding variable and the finite time stability of proposed method is proved using a new particular finite time condition in both reaching and sliding phases. In reaching phase new sliding mode controller is derived to guarantee the ...
متن کاملAdaptive Robust H∞ Control for Nonlinear Systems with Parametric Uncertainties and External Disturbances
This paper proposes a novel design method for the adaptive robust H∞ control problem of a class of nonlinear systems with parametric uncertainties and external disturbances, which combines adaptive control and robust H∞ control techniques. By the use of the parameter projection method in adaptive control, the adaptive control laws are derived. Based on Hamilton-Jacobi inequalities, the adaptive...
متن کاملSampled-data adaptive control for a class of nonlinear systems with parametric uncertainties ⋆
Sampled-data control systems have been prevailing in various applications, in parallel with the development of digital computers and its applications in control activities. At the same time, adaptation has proved to improve performance of a control algorithm, particularly when uncertainties involve in the model of the systems. In this paper, a stabilization problem for a class of nonlinear syst...
متن کاملAdaptive extremum seeking control of nonlinear dynamic systems with parametric uncertainties
We pose and solve an extremum seeking control problem for a class of nonlinear systems with unknown parameters. Extremum seeking controllers are developed to drive system states to the desired set-points that optimize the value of an objective function. The proposed adaptive extremum seeking controller is “inverse optimal” in the sense that it minimizes a meaningful cost function that incorpora...
متن کاملA Composite Energy Function Based Sub-Optimal Learning Control Approach for Nonlinear Systems with Time-Varying Parametric Uncertainties
In this paper, a novel composite energy function (CEF) is introduced to provide a general framework for incorporating system information along both time and learning repetition horizon. Based on the CEF, learning control is integrated with nonlinear sub-optimal control to enhance control performance for a class of nonlinear system with time-varying parametric uncertainties. Sub-optimal control ...
