ABSTRACT: This paper concerns the problem of output consensus in nonlinear non-minimum phase systems. The main contribution of the paper is to guarantee achieving consensus in the presence of unstable zero dynamics. To achieve this goal, an output redefinition method is proposed. The new outputs of agents are functions of original outputs and internal states and defined such that the dynamics o...

The origin of weakly bound objects like clusters and hypernuclei, observed in heavy-ion collisions, is theoretical experimental interest. It the focus experiments at BNL Relativistic Heavy Ion Collider (RHIC) Large Hadron (LHC) since it not evident how such can survive an environment whose hadronic decay products point to a temperature order 150 MeV. also one key research topics future faciliti...

The problem of tracking control of nonlinear systems whose the zero dynamics are unstable is addressed in this paper. It is shown that, using a novel cascade structure where the backstepping approach is given to stabilise the internal dynamics and the standard input output linearization to stabilise the external dynamics. Assuming high-gain feedback for the external dynamics, a stability analys...

In this paper we study the problem of tracking a reference signal from the H 1 point of view. As opposed to general H 1 problems, where only suboptimal solutions are obtained, we show that for both the full information and measurement feedback tracking problems the H 1-optimal solutions can be explicitly found. The results also indicate an interesting dichotomy between minimum phase and non-min...

This paper presents a trajectory tracking scheme for class of underactuated non-minimum phase marine vessels. Through proper coordinates transformations, the vessels model can be transformed into two-input-two-output strict-feedback form which general backstepping method applicable to solve control problem. To avoid possible singularity problem in recursive design, an AMO (asymptotic modificati...
