Case studies on passivity-based stabilisation of closed sets
نویسندگان
چکیده
We present a novel control design procedure for the passivity-based stabilization of closed sets which leverages recent theoretical advances. The procedure involves using part of the control freedom in order to enforce a detectability property, while the remaining part is used for passivity-based stabilization. The procedure is illustrated in four case studies of path following coordination for one or two kinematic unicycles, and variations of these problems. Among other things, we present a smooth global path following controller making the unicycle converge to an arbitrary closed and strictly convex curve, and a coordinated path following controller for two unicycles.

Passivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations
This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...
متن کاملOn Regular Generalized $delta$-closed Sets in Topological Spaces
In this paper a new class of sets called regular generalized $delta$-closed set (briefly rg$delta$-closed set)is introduced and its properties are studied. Several examples are provided to illustrate the behaviour of these new class of sets.
متن کاملA novel fuzzy multi-criteria decision-making methodology based upon the spherical fuzzy sets with a real case study
The choice of roll stabilization system is critical for many types of ships. For warships where operational activities are fast and the concept of time is very effective, determining the most appropriate of these systems is of particular importance. Some operations, such as the landing of the helicopter on board, are critical for naval ships. Unwanted rolling motion makes this difficult. In add...
متن کاملA remark on passivity-based and discontinuous control of uncertain nonlinear systems
We address the problem of robust stabilisation of nonlinear systems a!ected by time-varying uniformly bounded (in time) a$ne perturbations. Our approach relies on the combination of sliding mode techniques and passivity-based control. Roughly speaking we show that under suitable conditions the sliding mode variable can be chosen as the passive output of the perturbed system. Then we show how to...
متن کاملFiction and Politics of Islamophobia: A Case Study of Greg Hrbek’s Not on Fire, but Burning
Islamophobia is defined as a closed-minded hatred, fear or prejudice toward Islam and Muslims that result in discrimination, marginalization, and oppression. This phenomenon was strengthened after September 11 marked a watershed in the history of America. In the wake of 9/11, Islamophobia was promulgated in a plethora of textual and visual narratives, including novel. This paper studies Islamop...
