— This paper considers the stabilization problem for nonlinear retarded systems. The author has already proposed a finite spectrum assignment method for nonlinear retarded systems by extending the finite spectrum assignment for linear systems over commutative rings. In this paper, introducing a state predictor based on anticipating synchronization, we(More)
In the present study, a sliding mode control design method based on the finite spectrum assignment procedure is proposed. The finite spectrum assignment for retarded nonlinear systems can transform retarded nonlinear systems into delay-free linear systems via a variable transformation and a feedback, which contain the past values of the state. This method(More)
— In this paper, we address the tracking control problem for a unicycle-type mobile robot which is remotely controlled by a two-channel, delay-inducing communication network. A predictor-based control strategy capable of controlling the negative effects of the time-delay is proposed. Moreover, conditions are provided guaranteeing the local or global(More)
We study networks of diffusively time-delay coupled oscillatory units and we show that networks with certain symmetries can exhibit a form of incomplete synchronization called partial synchronization. We present conditions for the existence and stability of partial synchronization modes in networks of oscillatory units that satisfy a semipassivity property(More)
In this paper, we consider the consensus control problem for a multi-agent system (MAS) consisting of integrator dynamics with input and output time delays. First we investigate a consensus condition for the MAS with a linear controller without any delay compensation. After that, we propose a consensus controller with a state predictor to decrease the(More)
