Stabilization of non-admissible curves for a class of nonholonomic systems

, 2019
The problem of tracking an arbitrary curve in the state space is considered for underactuated driftless control-affine systems. This problem is formulated as the stabilization of a time-varying family of sets associated with a neighborhood of the ...

A simple method for shifting local dq impedance models to a global reference frame for stability analysis [PDF]

arXiv, 2017
Impedance-based stability analysis in the dq-domain is a widely applied method for power electronic dominated systems. An inconvenient property with this method is that impedance models are normally referred to their own local reference frame, and need to be recalculated when referring to a global reference frame in a given network.

Refer, Reuse, Reduce: Generating Subsequent References in Visual and Conversational Contexts [PDF]

arXiv, 2020
Dialogue participants often refer to entities or situations repeatedly within a conversation, which contributes to its cohesiveness. Subsequent references exploit the common ground accumulated by the interlocutors and hence have several interesting properties, namely, they tend to be shorter and reuse expressions that were effective in previous ...

Reference Phase Stabilizer for Distributed Underwater Sonar Systems

Sensors, 2018
An optical fiber is a promising approach for data and clock transmission in distributed underwater sonar systems. However, synchronization is a critical challenge in distributed sonar systems, which mandates accurate clock synchronization down to a sub ...

Model Reference Adaptive Control of Systems with Gain Scheduled Reference Models [PDF]

arXiv, 2014
Firstly, a new state feedback model reference adaptive control approach is developed for uncertain systems with gain scheduled reference models in a multi-input multi-output (MIMO) setting. Specifically, adaptive state feedback for output tracking control problem of MIMO nonlinear systems is studied and gain scheduled reference model system is used for

Adaptive Output Tracking Control with Reference Model System Uncertainties [PDF]

arXiv
This paper develops adaptive output tracking control schemes with the reference output signal generated from an unknown reference system whose output derivatives are also unknown. To deal with such reference system uncertainties, an expanded adaptive controller structure is developed to include a parametrized estimator of the equivalent reference input
