This paper presents a general uncertain complex singular dynamical network model. Since the nodes of the network are singular systems, the overall network can only be described by a singular model. Due to the flexible of singular systems in describing practical applications, the complex singular dynamical network has more applications than the regular complex network in which the nodes are described...
This paper describes an integrated controller for handling the problem on rudder roll stabilization (RRS) of ship model uncertainty and hard nonlinearities about input rate and magnitude saturations. According to the state space model of ship, a generalized predictive controller (GPC) is deduced. The controller is adjusted by fuzzy gain scheduler (FGS), which is optimized with genetic algorithms (GA)...
In this paper we study the global robust output regulation problem for a class of nonlinear systems by output feedback control. The class of systems possesses nonlinear zero-dynamics and, is thus considerably larger than systems studied in the existing literature. As an illustration of our approach, we have applied our approach to the global robust asymptotic tracking problem of the hyperchaotic Lorenz...
This paper studies a class of uncertain discrete event systems over the max-plus algebra, where system matrices are unknown but are convex combinations of known matrices. These systems model a wide range of applications, for example, transportation systems with varying vehicle travel time and queueing networks with uncertain arrival and queuing time. This paper presents computational methods for different...
In this paper the design of an optimal nonlinear Hinfin (NL-Hinfin) controller for flexible joint robot (FJR) with bounded input control and fast tracking is presented. Moreover, FJR robot link positions are controlled without any undershoot and overshoot. Also, this paper discusses the robust L2-gain performance synthesis problem for uncertain FJRs which have nonlinear dynamic. So, the Hamilton-Jacobi...
This paper presents robust passivity-based control (RPBC) laws for a class of weakly minimum phase nonlinear uncertain systems which can be either of nonlinear affine or relative-degree-1. The proposed RPBC laws contain two objectives: one is to passificate the controlled systems; the other is to asymptotically stabilize them. The sufficient conditions are also established for the proposed RPBC. The...
In this study, a robust algorithm with a fuzzy sliding model controller (FSMC) is used to synchronization of a Duffing-Holmes system. The robust algorithm is an output factor of the fuzzy sliding model controller. The control rules of FSMC are based on the Lyapunov stability theorem. The objective of synchronization is to study a master-and-slave system to be synchronized with both uncertainties and...
This paper considers the problem of robust control for a class of uncertain time-varying dynamical systems with real time-varying parameter uncertainity. Interest is focused on the design of linear dynamic output feedback control and two problems are addressed. The first one is the robust stabilization and the other is the problem of robust H?? like performance. A technique is proposed for designing...
