This paper proposes an approximate output tracking control for a class of PWM switched dc-dc converters driving LED lighting systems. The proposed model provides a discrete-time response of the one-cycle average (OCA) value of output signal of the system. Typically, the proposed model has unstable zero dynamics, as well as a nonlinear dependence on the duty ratio control input. Using scheduled ...

This paper addresses the problem of the local state feedback stabilization of a class of nonlinear systems with nonminimum phase zero dynamics. A new technique, namely, the Lyapunov function with homogeneous derivative along solution curves has been developed to test the approximate stability of the dynamics on the center manifold. A set of convenient sufficient conditions are provided to test ...

This two-part paper considers strategic topology switching for the second-order multi-agent system under attack. In Part II, we propose a strategy on switching topologies to reveal zero-dynamics attack. We first study the detectability of zero-dynamics attack for the second-order multi-agent system under switching topology, which has requirements on the switching times and switching topologies....

We examine the relation between topological entropy, invertability, and prediction in topological dynamics. We show that topological determinism in the sense of Kamińsky Siemaszko and Szymański imposes no restriction on invariant measures except zero entropy. Also, we develop a new method for relating topological determinism and zero entropy, and apply it to obtain a multidimensional analog of ...

The current study aimed to examine the relationship between personality traits and interpersonal states. Eighty undergraduate participants were administered trait inventories, then 40 dyads video recorded doing collaborative tasks. These recordings coded for moment-to-moment communion agency using Continuous Assessment of Interpersonal Dynamics. Actor-Partner Interdependence Modeling was used u...
