Complex embedded computer systems can encompass multiple application subsystems, such as a multimedia, a powertrain, a comfort and a safety subsystem in the in-vehicle electronic system of a typical premium car. Information exchanges between these application subsystems are essential to realize composite services that involve more than one application subsystem and to reduce redundant computati...

Multirate digital decentralized control design is presented for linear timeinvariant systems with interaction between subsystems. The design technique, implemented in multirate digital control, eventually allows us to separately design controllers for each subsystem without considering interaction between them. The resulting closed-loop system with interaction between subsystems being eliminate...

A plant-wide control strategy based on integrating linear model predictive control (LMPC) and nonlinear model predictive control (NMPC) is proposed. The hybrid method is applicable to plants that can be decomposed into approximately linear subsystems and highly nonlinear subsystems that interact via mass and energy ̄ows. LMPC is applied to the linear subsystems and NMPC is applied to the nonlin...

System design is typically done in VHDL to facilitate top-down design and to enable the mapping of a design to many implementations. Reusabil-ity of subsystems to date has largely been performed with libraries of synthesizable VHDL subsystems. This paper presents recommended extensions to VHDL to allow the VHDL designer to interact with nonsynthesizable subsystems while still designing in VHDL....

Consider a state of a system with several subsystems. The entropies of the reduced state on different subsystems obey certain inequalities, provided there is an equivalence relation, and a function measuring volumes or weights of subsystems. The entropy per unit volume or unit weight, the mean entropy, is then decreasing with respect to an order relation of the subsystems, defined in this paper...

The design of robotic systems is a multidisciplinary effort requiring input from engineers and scientist in a variety of fields. Throughout the design process, numerous engineering models are developed to describe the various subsystems that make up a robotic device. We will present a biologically inspired robotic snake as a case study to demonstrate the typical engineering models that comprise...

Abstract: Stability analysis and stabilization synthesis problems of the singularly perturbed switched systems (SPSSs) are investigated in this paper. First, stability of the SPSS with stable subsystems is discussed by using an average dwell time approach with a full-order piecewise Lyapunov function. Then, the result is extended to the situation that not all the subsystems are Hurwitz stable. ...

Many complex physical systems are the interconnection of lower-dimensional subsystems. For such systems, distributed stability analysis and observer design presents several advantages with respect to centralized approaches, such as modularity, easier analysis and design, and reduced computational complexity. Applications include distributed process control, traffic and communication networks, a...
