This paper, at the first time, considers the problem of decentralized variable structure control of complex giant singular uncertainty systems by using the property of diagonally dominant matrix and Frobenius-Person theorem. The splendid selection of switching manifold for each subsystem makes the design relatively straightforward and can be easily realized. An illustrate example is given.

The ship course / roll system is a nonlinear and strongly coupled system. Based on the parameter uncertainty of the ship course / roll coupled model, a decentralized variable structure control algorithm is adopted. The interconnection matrices are regarded as the parameter matrix of the nominal system under the known condition of the interconnection terms. The global asymptotic stability of the decentralized variable structure control algorithm is achieved. The simulation results show that, the proposed control method can control the ship yaw and roll very efficiently with high accuracy, conciseness and would be easy to be realized.

In this paper, the decentralized variable structure control (DVSC) of uncertain large-scale distributed parameter systems with dead-zone nonlinearity in the input and time-varying delay in the interconnection is studied. The DVSC law for the interconnected systems is realized independently through the delay terms and drives the state trajectory of the system to the sliding manifold in finite time. A sufficient condition of asymptotic stability for the sliding motion is derived.

decentralized tracking for a class of interconnected nonlinear systems using fuzzy variable structure control with application to a drill and dry jet mixing machine

TRANSACTIONS OF THE INSTITUTE OF MEASUREMENT AND control 2001年第2期23卷 102-126页

作者： Cheng, XY Leung, TP Hong Kong Polytech Univ Dept Engn Mech Kowloon Hong Kong Peoples R China

In this paper ive have presented a novel decentralized fuzzy variable structure controller (DFVSC) for the tracking problem of a class of uncertain interconnected nonlinear systems. The decentralized variable structure control principle is utilized to dear with model uncertainties, nonlinear interactions between subsystems, control input sain uncertainties and external disturbances. A fuzzy logic function is applied to eliminate the chattering problem and improve the tracking performance. The proposed DFVSC is applied to a drill and dry jet mixing machine. The performances of: the proposed DFVSC are compared with the conventional decentralized variable structure control (DVSC) and suboptimal PID control (SPIDC) by computer simulation. Simulation results show that the proposed DFVSC can achieve excellent transient performance, faster response, better precision and good robustness against system parameter uncertainties, various airflow conditions and uncertain time-varying external disturbance.

Designing stable finite state machine behaviors using phase plane analysis and variable structure control

JOURNAL OF INTELLIGENT & ROBOTIC SYSTEMS 2003年第4期36卷 349-370页

This paper discusses how phase plane analysis can be used to describe the overall behavior of single and multiple autonomous robotic vehicles with finite state machine rules. The importance of this result is that we can begin to design provably stable group behaviors from a set of simple control laws and appropriate switching points with decentralized variable structure control. The ability to prove stable group behavior is especially important for applications such as locating military targets or land mines. In this paper, we demonstrate how phase plane analysis has been used to explain the behavior of a 16 cm(3) autonomous line-tracking robot with four finite states. After which, the analysis is extended to include the design of a decentralized variable structure controller that guides multiple vehicles to a goal while avoiding each other.

Design of large-scale time-delayed systems with dead-zone input via variable structure control

To deal with time delay in the interconnection and dead-zone nonlinearity in the input, a new decentralized variable structure control (DVSC) law is proposed for a class of uncertain large-scale system (LSS) in this paper. The developed DVSC for the interconnected systems is realized independently through the delay terms. The applied control effort of the DVSC law is always out of the dead-band to eliminate the effects arisen from the dead-zone nonlinearity in the input function. In the sliding mode, it can be seen that the invariance condition also holds. It is worth noting that the traditional large-scale time-delayed system is only a special case in this work. Illustrative examples are given to verify the validity of the developed controller. (c) 2005 Elsevier Ltd. All rights reserved.
