Modeling and Analysis of Hybrid Control Systems
نویسنده
چکیده
A hybrid control system contains both continuous-time and discrete event components. Specifically, the plant is a continuoustime system modeled by differential equations, and the controller is a discrete event system modeled by an automaton. This paper presents a framework for modeling hybrid control systems including the necessary interface between the plant and controller. A method to represent the entire system as a discrete event system is shown, and the concept of determinism is used to analyze hybrid control system behavior and guide in hybrid control system design.

متن کاملVoltage Regulation of DC-DC Series Resonant Converter Operating in Discontinuous Conduction Mode: The Hybrid Control Approach
Dynamic modeling and control of dc-dc series resonant converter (SRC) especially when operating in discontinuous conduction mode (DCM) is still a challenge in power electronics. Due to semiconductors switching, SRC is naturally represented as a switched linear system, a class of hybrid systems. Nevertheless, the hybrid nature of the SRC is commonly neglected and it is modeled as a purely contin...

متن کاملUsing Interval Petri Nets and Timed Automata for Diagnosis of Discrete Event Systems (DES)
A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...
