this paper evaluates a new and simple controller design method based on qft (quantitative feedback theory) for a two-link manipulator whose first link is rigid and the second is flexible. a piezoelectric patch is attached to the surface of the flexible link for vibration suppression of it. this system is modeled as a nonlinear multi-input multi-output (mimo) control systems whose inputs are two...

Single quantum dot detection sensitivity can be demonstrated with high spatio-temporal resolution using a combined approach of Fluorescence Correlation Spectroscopy (FCS) , Multi-Channel Scaling (MCS) and Nonlinear (multiphoton-excited) Laser Scanning Microscopy (NLSM) demonstrating the unique opportunities of multi-modality nonlinear laser microscopy in conjunction with quantum dots for probin...

In this paper we apply subspace methods to the identification of a class of multi-input multi-output discrete-time nonlinear time-varying systems. Specifically, we study the identification of systems that are nonlinear in measured data and linear in unmeasured states. We present numerical simulations to demonstrate the efficacy of the method.

This work investigates the consensus problem for multi-agent nonlinear systems through the distributed real-time nonlinear receding horizon control methodology. With this work, we develop a scheme to reach the consensus for nonlinear multi agent systems under fixed directed/undirected graph(s) without the need of any linearization techniques. For this purpose, the problem of consensus is conver...

In this paper, the formation control problem of multi-agent systems with nonlinear dynamic is considered. Output regulation problem of nonlinear systems is generalized to the formation control problem of nonlinear multi-agent systems. The reference inputs or disturbance signals are generated by an exo-system, which can be considered as an active leader in the considered multi-agent systems. Whe...

In this paper, robust stability and output tracking performance of multi-input multi-output (MIMO) nonlinear feedback system are considered by using operator based robust right coprime factorization approach. Sufficient conditions for the MIMO nonlinear system to be robustly stable are derived, and tracking filters are designed to realize the desired tracking performance. Finally, a simulation ...
