Robust guaranteed-cost sliding control for brushless DC motors by LMI

International Journal of Modelling, Identification and Control, 2012
Two state feedback sliding mode control schemes are developed for position control for brushless DC motor drives. The first controller design achieves the desired swiftness of response. In addition to swiftness, the second controller drastically reduces system’s chattering by adding the guaranteed cost constraint.

Moving Target Landing of a Quadrotor Using Robust Optimal Guaranteed Cost Control

IEEE/CAA Journal of Automatica Sinica, 2023
Dear Editor, This letter proposes a robust control strategy for the autonomous landing of a quadrotor on a moving target. Specifically, a force command that consists of a cascade dynamics estimator and an optimal guaranteed cost control law is exploited for the position-loop tracking.

Robust guaranteed cost control for a nonlinear neutral system with infinite delay

2015 European Control Conference (ECC), 2015
The paper presents new results for the robust guaranteed cost control problem for a nonlinear neutral system having infinite delay with a given quadratic cost function. A delay dependent stability criterion, based on a model transformation technique, is proposed.

Adaptive Robust Guaranteed Cost Control with Application to Yaw Control of Helicopter

2007 International Conference on Machine Learning and Cybernetics, 2007
This paper deals with the problem of robust tracking control with adaptation mechanism to improve transient performance in time-response. A linear time-invariant system with time-varying ellipsoidal uncertainty is considered. The proposed controller affinely depends on the estimations of parameters, which are adjusted on-line according to the error ...

Robust guaranteed cost control of networked control systems with time delay

2008 Chinese Control and Decision Conference, 2008
Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems. Based on the controlled process that is linear time-invariant system, the network induced delay is viewed as time-varying parameter uncertainties.

Robust guaranteed cost rate anti‐bump switching control for switched systems

International Journal of Robust and Nonlinear Control, 2021
AbstractA multi‐objective switching control strategy is presented in this paper to capture both the robust guaranteed cost (GC) performance and the rate anti‐bump switching performance of switched systems (SSs). The rate anti‐bump switching performance refers to the alleviation of big instantaneous jumps in the switched system rate.

Robust guaranteed-cost controllers for networked systems with varying delays

18th Mediterranean Conference on Control and Automation, MED'10, 2010
This paper is concerned with the synthesis of robust guaranteed-cost controllers for networked systems operating under uncertain, bounded, time-varying transmission delays. The uncertainty of the transmission delay results in an uncertain discrete-time networked controlled system (NCS).

Robust optimal guaranteed cost control for 2D discrete systems

IEE Proceedings - Control Theory and Applications, 2001
The guaranteed cost control problem is studied for a class of 2D discrete uncertain systems in the Fornasini-Marchesini state space setting. The uncertainty is assumed to be norm-bounded. Based on the guaranteed cost controller for 1D differential/difference systems, the notion of the guaranteed cost control problem for 2D discrete systems is proposed.

Decentralized robust guaranteed cost control for multimachine power systems

14th International Conference on Sciences and Techniques of Automatic Control & Computer Engineering - STA'2013, 2013
In this paper, we investigate the problem of the decentralized robust stabilizing control approach and mainly the decentralized robust guaranteed cost control for robust stabilization of interconnected multimachine power systems. The proposed feedback control schemes are developed to ensure the asymptotic stability of the nonlinear uncertain large ...

Guaranteed Cost Robust Control for Switch System with Sector Uncertainty

2006 Chinese Control Conference, 2006
This paper focuses on the state feedback guaranteed cost robust control of discrete-time switched system with sector uncertainty. The purpose is to design a state feedback control law such that the close-loop system is asymptotically stable and the closed-loop cost function value is not more than a specified upper bound for all admissible sector ...
