The numerical simulation of non-smooth hybrid systems exhibiting chattering behavior requires high computational costs. In the worst case, the simulation appears to come to a halt, since infinitely many discrete transitions would need to be simulated. In this paper we present an FMI-based framework and prototypical implementation for robust and reliable detection and elimination “On the Fly” of...

Chattering alarms, which repeatedly and rapidly make transitions between alarm and normal states in a short time period, are the most common form of nuisance alarms that severely degrade the performance of alarm systems for industrial plants. One reason for chattering alarms is the presence of oscillation in process signals. The paper proposes an online method to promptly detect the chattering ...

Professor Utkin in his discussion paper proposed an example showing that the amplitude of chattering caused by the presence of parasitic dynamics in systems governed by FirstOrder Sliding-Mode Control (FOSMC) is lower than the obtained using Super-Twisting Algorithm (STA). This example served to motivate this research reconsidering the problem of comparison of chattering magnitude in systems go...

Chaotic chattering behaviors of DC-DC converters are caused by the nonlinearity of the switching operation which is an essential characteristics of the power electronics circuits. In this paper the bifurcation and the appearance of the chaotic chattering in the discontinuous current conduction mode of a DC-DC buck converter are discussed experimentally. Moreover, a method for controlling chaoti...

The possibility that a hybrid simulation model can change its state infinitely often in a finite time interval impacts negatively, or even disables, the ability to simulate some hybrid systems. This behavior also known as chattering occurs in models that can switch continuously between different modes of operation. In this paper we provide two solutions to different kinds of chattering behavior...

Considering pitch channel simplified model of missile control system, a VSCL(variable structure control law) is designed by using overload and angle velocity signals. Especially, an analysis is proposed for the situation of equal control with uncertainties. An integral action is introduced to compensate the uncertainties and a soft function is adopted to solve the chattering problem of VSC. Fin...

In conventional sliding-mode control systems, the sliding-mode motion is of reduced order. Two main problems hindering the application of the sliding-mode control are the singularity in terminal slidingmode control systems and the chattering in both the conventional linear sliding-mode and the terminal sliding-mode control systems. This paper proposes a chattering-free full-order terminal-slidi...
