Observer Design for Discrete-Time Switching Nonlinear Models

Zsofia Lendek, Paula Raica, Jimmy Lauber, Thierry-Marie Guerra

Switched systems are often described by continuous and discrete dynamics as well as their interactions. Although results are available for linear switching systems, for nonlinear switching models few results exist. In this chapter, we consider observer design for discrete-time switching nonlinear…

On the Observation Analysis and Observer Design for a Class of Hybrid Continuous-Discrete Dynamic System

Noureddine Manamanni, Mohamed Djemai, Jean-Pierre Barbot

This chapter deals with observability conditions and state observer design for a class of hybrid systems whose the continuous part combines continuous and discrete dynamics. The main contribution of the work lies in the performed observability conditions for this class of systems and the design of…

Performance comparison of sliding mode observers for back EMFs based speed estimation in PMSM

Suneel Kumar Kommuri, Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort, Sivanagaraja Tatinati

This paper proposes a second-order high-speed sliding mode (SHSM) observer and compares the performance with the recent higher-order sliding mode (HOSM) observer for the problem of sensorless speed estimation in the permanent magnet synchronous motor (PMSM). In which, a sigmoid function is…

An adaptive modified super-twisting sliding mode controller: Applied to the active suspension system

Jagat Jyoti Rath, Suneel Kumar Kommuri, Kalyana Chakravarthy Veluvolu, Michael Defoort, Sivanagaraja Tatinati

A robust higher order sliding mode algorithm combining the merits of the modified super-twisting algorithm and the adaptive super-twisting algorithm has been proposed for a class of nonlinear uncertain systems in this article. For a class of linearly growing perturbations whose upper bounds are not…

Towards Vertical and Horizontal Extension of Shared Control Concept

Marie-Pierre Pacaux-Lemoine, Makoto Itoh

Goals of shared control usually focus on the sharing of the action. Several examples such as shared control in robotics, in car driving, in wheelchair control highlight the interest for Human operator to be able to take part in the control of a process in the same way as assistance systems.…

Shared Control Framework Applied for Vehicle Longitudinal Control in Highway Merging Scenarios

Chunshi Guo, Chouki Sentouh, Jean-Christophe Popieul, Soualmi Boussaad, Jean-Baptiste Haué

This paper describes the design of a shared control framework for vehicle longitudinal control applied in Automated Driving (AD) systems. Due to the complexity of automation design, highway merging scenario is firstly selected as the use case for system's functional design. Besides the…

A multi-objective approach for software/hardware partitioning in a multi-target tracking system

Ihsen Alouani, Braham Lotfi Mediouni, Smail Niar

Heterogeneous Multiprocessor System-on-Chips (MPSoCs) are getting increasingly used to cope with new embedded applications performance requirements. In such systems, the promising cohabitation of processing elements (PEs) having different aspects allows designers to better exploit the synergy of…

Fault detection based on higher-order sliding mode observer for a class of switched linear systems

Jérémy van Gorp, Michael Defoort, Mohamed Djemai, Kalyana Chakravarthy Veluvolu

This study considers the fault detection problem for a class of switched linear systems when the observer matching condition is not satisfied. Without using decoupling transformations, a residual signal, based on reduced order sliding mode observers, is introduced for the detection of faults which…
