Contouring Error Bounded Control for Biaxial Switched Linear Systems

no code implementations8 Apr 2024 Meng Yuan, Ye Wang, Chris Manzie, Zhezhuang Xu, Tianyou Chai

To address the need for improved contouring accuracy in industrial machines with position-dependent structural flexibility, this paper introduces a novel contouring error-bounded control algorithm for biaxial switched linear systems.

A Control Barrier Function Composition Approach for Multi-Agent Systems in Marine Applications

no code implementations21 Mar 2024 Yujia Yang, Chris Manzie, Ye Pu

The agents within a multi-agent system (MAS) operating in marine environments often need to utilize task payloads and avoid collisions in coordination, necessitating adherence to a set of relative-pose constraints, which may include field-of-view, line-of-sight, collision-avoidance, and range constraints.

Gradient-enhanced deep Gaussian processes for multifidelity modelling

no code implementations25 Feb 2024 Viv Bone, Chris van der Heide, Kieran Mackle, Ingo H. J. Jahn, Peter M. Dower, Chris Manzie

Multifidelity models integrate data from multiple sources to produce a single approximator for the underlying process.

Stochastic Co-design of Storage and Control for Water Distribution Systems

no code implementations21 Aug 2023 Ye Wang, Erik Weyer, Chris Manzie, Angus R. Simpson, Lisa Blinco

To address these limitations, we introduce a method to simultaneously design infrastructure and develop control parameters, the co-design problem, with the aim of improving the overall efficiency of the system.

Sub-Optimal Moving Horizon Estimation in Feedback Control of Linear Constrained Systems

no code implementations13 Apr 2023 Yujia Yang, Chris Manzie, Ye Pu

Moving horizon estimation (MHE) offers benefits relative to other estimation approaches by its ability to explicitly handle constraints, but suffers increased computation cost.

Asynchronous Event-Triggered Control for Non-Linear Systems

no code implementations25 Nov 2022 Daniel A. Williams, Airlie Chapman, Chris Manzie

With the increasing ubiquity of networked control systems, various strategies for sampling constituent subsystems' outputs have emerged.

Lazy Probabilistic Roadmaps Revisited

no code implementations28 Sep 2022 Miquel Ramirez, Daniel Selvaratnam, Chris Manzie

This paper describes a revision of the classic Lazy Probabilistic Roadmaps algorithm (Lazy PRM), that results from pairing PRM and a novel Branch-and-Cut (BC) algorithm.

Real-Time Distributed Model Predictive Control with Limited Communication Data Rates

no code implementations26 Aug 2022 Yujia Yang, Ye Wang, Chris Manzie, Ye Pu

The cyclic-small-gain theorem is used to derive sufficient conditions on the quantization parameters for guaranteeing the stability of the system under a limited data rate.

Data-driven Predictive Tracking Control based on Koopman Operators

1 code implementation25 Aug 2022 Ye Wang, Yujia Yang, Ye Pu, Chris Manzie

Constraint handling during tracking operations is at the core of many real-world control implementations and is well understood when dynamic models of the underlying system exist, yet becomes more challenging when data-driven models are used to describe the nonlinear system at hand.

Explicit Time-Optimal Speed Profiles for Planar Paths with Monotone Curvature

no code implementations25 Aug 2022 Daniel Selvaratnam, Michael Cantoni, Chris Manzie

Minimum-time speed profiles are constructed for planar paths with smooth strictly-monotonic signed curvature, subject to constraints on velocity, normal acceleration and tangential acceleration.

Individual and Team Trust Preferences for Robotic Swarm Behaviors

no code implementations28 Mar 2022 Elena M Vella, Daniel A Williams, Airlie Chapman, Chris Manzie

We formulate a linear optimization problem to locate a trusted behavior in the feature space.

Temporal Logic Planning for Minimum-Time Positioning of Multiple Threat-Seduction Decoys

no code implementations17 Jun 2021 Tony A. Wood, Mitchell Khoo, Elad Michael, Chris Manzie, Iman Shames

The task of a decoy reaching a state in which the lock of the assigned threat can be broken is formulated as a temporal logic specification.

Ordinal Optimisation for the Gaussian Copula Model

1 code implementation5 Nov 2019 Robert Chin, Jonathan E. Rowe, Iman Shames, Chris Manzie, Dragan Nešić

We present results on the estimation and evaluation of success probabilities for ordinal optimisation over uncountable sets (such as subsets of $\mathbb{R}^{d}$).
