Convergence of Probability Measures

Building Leadership Effectiveness This program encourages leaders to develop practices that transform values into action, vision into realities, obstacles into innovations, and risks into rewards. Participants will be introduced to the five practices of exemplary leadership: modeling the way, inspiring a shared vision, challenging the process, enabling others to act, and encouraging the heart Coaching & Communicating for Performance Coaching & Communicating for Performance is a highly interactive program that will give supervisors and managers the opportunity to build skills that will enable them to share expectations and set objectives for employees, provide constructive feedback, more effectively engage in learning conversations, and coaching opportunities. Skillful Conflict Management for Leaders As a leader, it is important to understand conflict and be effective at conflict management because the way conflict is resolved becomes an integral component of our university’s culture. This series of conflict management sessions help leaders learn and put into practice effective strategies for managing conflict.

We focus on the robust H/sub /spl infin//control analysis and synthesis for uncertain switched linear systems. It is shown that the quadratic stability of one associated non-switched uncertain combination linear system implies the feasibility of H/sub /spl infin// control problem for an uncertain switched linear system. Then, the robust H/sub /spl infin// control synthesis via switched state feedback is studied. A switched state feedback controller is designed to quadratically stabilize the plant and achieve a prescribed disturbance attenuation level /spl gamma/ for all admissible uncertainties simultaneously. All the results in this paper can be regarded as an extension of some existing results for both switched and non-switched systems.

Robust H/sub /spl infin//control and quadratic stabilization of uncertain switched linear systems

The problem of stabilization of networked control systems (NCSs) with time-varying transmission delays is investigated. The time-varying delays lie in any two adjoining sampling instants of the plant. A technique is proposed for designing stabilizing controllers by converting NCSs with time-varying transmission delays into parameter uncertain systems with constant input delay, then the theory of robust stabilization of delay systems can be applied to solving this problem. Sufficient condition on stabilization of such NCSs is developed in terms of linear matrix inequality.

Stabilization of networked control systems with transmission delays

In this paper, we study the consensus problem for networked dynamic systems with arbitrary initial states, and present some structural characterization and direct construction of consensus functions. For the consensus problem under similar transformation, we establish some necessary and sufficient conditions by exploiting the structure of consensus functions. Finally, we discuss the consensus problem for dynamic systems under switching by using the common Lyapunov function method.

Algebraic Characterizations of Consensus Problems for Networked Dynamic Systems

This paper formulates the mathematical model of a biped that is capable of dynamic walking gaits. The model consists of hip actuation, segmented legs, flat feet and torsional spring based passive ankle stiffness. Using numerical simulations on the proposed model, we find that from the view of stability, there is optimal foot-ankle ratio of the flat-foot bipeds. The results indicate that the human foot proportion is indeed better optimized for dynamic bipedal walking than that of apes, further suggesting the current state of human foot is to some extent the product of positive selection for more stable bipedal locomotion during the evolution of the foot.

Modeling and stability analysis of human normal walking with implications for the evolution of the foot

This paper addresses the problem of robust stability and stabilization of a class of nonlinear switched systems when each subsystem is not stabilized by a designed single static output feedback. Both the condition on robust stability only via switching and the condition on switched static output feedback controllers are expressed in terms of matrix inequalities. These conditions are derived by multiple Lyapunov functions technique and the switching rules adopted are state-dependent. All these results can be regarded as an extension of some existing results for non-switched systems.
