“…The decentralized tracking control problem is studied for a class of interconnected stochastic nonlinear systems in [21], where the result obtained can only guarantee that the closed-loop system is practically stable. A smooth dynamic output feedback control is proposed for the case of multiple time-delay systems with nonlinear uncertainties in [22]. However, it is based on dynamic feedback, which increases the system dimension as well as the computational complexity.…”

In this paper, a class of interconnected systems is considered, where the nominal isolated systems are fully nonlinear. A robust decentralised sliding mode control based on static state feedback is developed. By local coordinate transformation and feedback linearization, the interconnected system is transformed to a new regular form. A composite sliding surface which is a function of the system state variables is proposed and the stability of the corresponding sliding mode dynamics is analysed. A new reachability condition is proposed and a robust decentralised sliding mode control is then designed to drive the system states to the sliding surface in finite time and maintain a sliding motion thereafter. Both uncertainties and interconnections are allowed to be unmatched and are assumed to be bounded by nonlinear functions. The bounds on the uncertainties and interconnections have more general forms when compared with existing work. A MATLAB simulation example is used to demonstrate the effectiveness of the proposed method.

Summary In this paper, a class of interconnected systems is considered, where the nominal isolated systems are fully nonlinear. A robust decentralized sliding mode control based on static state feedback is developed. By local coordinate transformation and feedback linearization, the interconnected system is transformed to a new regular form. A composite sliding surface which is a function of the system state variables is proposed and the stability of the corresponding sliding mode dynamics is analyzed. A new reachability condition is proposed and a robust decentralized sliding mode control is then designed to drive the system states to the sliding surface in finite time and maintain a sliding motion thereafter. Both uncertainties and interconnections are allowed to be unmatched and are assumed to be bounded by nonlinear functions. The bounds on the uncertainties and interconnections have more general forms when compared with existing work. A MATLAB simulation example is used to demonstrate the effectiveness of the proposed method.

“…The main results in [38][39][40] mean that the state variables are unavailable in the measurement process, thus the output feedback control has been investigated. From the above analysis, it can be seen that the output feedback is effective than the state feedback [41][42][43], but some strict design conditions should be considered in static feedback [44,45]. Thus, the dynamic output feedback was proposed [46][47][48].…”
