Dynamic sliding mode control for nonlinear parameter‐varying systems

International Journal of Robust and Nonlinear Control, 2021
AbstractThis article deals with the dynamic sliding mode control (SMC) problem for unmatched nonlinear parameter‐varying systems. The unmatched nonlinear model refers to the systems matrices of control input and nonlinearity terms having inconsistent values and structures. A linear sliding surface function is constructed, and the resulting sliding mode

Nonlinear Optimal Control for Parameter-Dependent Polynomial Nonlinear Systems

2007 IEEE International Conference on Control and Automation, 2007
In this paper, we address the nonlinear optimal control problem for parameter-dependent nonlinear systems with polynomial vector fields. Based on the state dependent coefficient form, sufficient conditions to guarantee the closed-loop stability and bounded performance index are presented as state dependent linear matrix inequalities, which can be ...

Parameter Estimation and Nonlinear Predictive Control for RTP

IFAC Proceedings Volumes, 1994
Abstract Parameter estimation of a nonlinear dynamic model for a rapid thermal processing system is performed. A model transformation is presented that significantly improves the conditioning of the control system. Simulations of nonlinear QDMC demonstrate the viability of controllers based on quadratic programming techniques in terms of computation ...

Oscillatory control parameters in nonlinear chaotic systems

Physica Scripta, 2013
For a better understanding of the role of control parameters in nonlinear dynamical systems, we examined numerically the effect of the oscillatory control parameter D?=?C0?cos(?1t) on the Lorenz model for a dynamo, where C0 and ?1 are the driving amplitude and frequency, respectively.

Active Parameter Control of Nonlinear Vibrating Structures

Journal of Applied Mechanics, 1989
A simple, yet efficient method is presented for the on-line vibration control of nonlinear, multidegree-of-freedom systems responding to arbitrary dynamic environments. The procedure uses nonlinear auxiliary mass dampers with adjustable motion-limiting stops located at selected positions throughout a given nonlinear system.

On control of nonlinear distributed parameter bioreactors

Mathematics and Computers in Simulation, 1994
Abstract A distributed parameter fixed-bed bioreactor model with axial diffusion is presented. An orthogonal collocation method is applied to obtain a lumped parameter model, i.e. a system of ordinary differential equations, which consists of one subset for the biomass concentration and the other for the substrate concentration.

Adaptive Control Of Nonlinear Distributed Parameter Systems

International Journal of Modelling and Simulation, 1999
A finite dimensional model is derived for a class of nonlinear distributed parameter systems using the orthogonal collocation method This model is linearizable via state feedback. To cope with both parametric and dynamic uncertainties of the finite dimensional model, an adaptive control algorithm is proposed The adaptation laws are derived based on ...

Parameter Convergence for Adaptive Control in Nonlinear System

2020 Australian and New Zealand Control Conference (ANZCC), 2020
Feedback linearization uses an effective linearizing control to make the input-output dynamics of a nonlinear plant linear such that various linear control strategies can be applied for tracking the output trajectories to the desired one. One of the key open issues in adaptive control of feedback linearizable structures is the estimation of the ...
