  • Approximation of achievable robustness limit based on sensitivity inversion 
    Cho, Namhoon; Lee, Hae-In (AIAA, 2023-11-07)
    Introduction: The sensitivity function, defined as the closed-loop transfer function from the exogenous input to the tracking error, is central to the multi-objective design and analysis of a feedback control system. Its ...
  • Concurrent learning adaptive control with directional forgetting 
    Lee, Hae-In; Shin, Hyo-Sang; Tsourdos, Antonios (IEEE, 2019-04-17)
    This paper proposes a new concurrent learning-based adaptive control algorithm. The main objective behind our proposition is to relax the persistent excitation requirement for the stability guarantee, while providing the ...
  • Cooperative control of multi-uavs under communication constraints. 
    Lee, Hae-In (2018-10)
    This research aims to develop an analysis and control methodology for the multiple un-manned aerial vehicles (UAVs), connected over a communication network. The wireless communication network between the UAVs is vulnerable ...
  • EuroDRONE, A European unmanned traffic management testbed for U-space 
    Lappas, Vaios; Zoumponos, Giorgos; Kostopoulos, Vassilis; Lee, Hae-In; Shin, Hyo-Sang; Tsourdos, Antonios; Tantardini, Marco; Shomko, Dennis; Munoz, Jose; Amoratis, Epameinondas; Maragkakis, Aris; Machairas, Thomas (MDPI, 2022-02-18)
    EuroDRONE is an Unmanned Traffic Management (UTM) demonstration project, funded by the EU’s SESAR organization, and its aim is to test and validate key UTM technologies for Europe’s ‘U-Space’ UTM program. The EuroDRONE UTM ...
  • Parameter-robust linear quadratic Gaussian technique for multi-agent slung load transportation 
    Lee, Hae-In; Yoo, Dong-Wan; Lee, Byung-Yoon; Moon, Gun-Hee; Lee, Dong-Yeon; Tahk, Min-Jea; Shin, Hyo-Sang (Elsevier, 2017-09-14)
    This paper copes with parameter-robust controller design for transportation system by multiple unmanned aerial vehicles. The transportation is designed in the form of string connection. Minimal state-space realization of ...
  • A probabilistic–geometric approach for UAV detection and avoidance systems 
    Lee, Hae-In; Shin, Hyo-Sang; Tsourdos, Antonios (MDPI, 2022-11-27)
    This paper proposes a collision avoidance algorithm for the detection and avoidance capabilities of Unmanned Aerial Vehicles (UAVs). The proposed algorithm aims to ensure minimum separation between UAVs and geofencing with ...
  • Sample greedy based task allocation for multiple robot systems 
    Shin, Hyo-Sang; Li, Teng; Lee, Hae-In; Tsourdos, Antonios (Springer, 2022-08-13)
    This paper addresses in-schedule dependent task allocation problems for multi-robot systems. One of the main issues with those problems is the inherent NP-hardness of combinatorial optimisation. To handle this issue, this ...
  • UAV collision avoidance considering no-fly-zones 
    Lee, Hae-In; Shin, Hyo-Sang; Tsourdos, Antonios (Elsevier, 2021-04-14)
    This paper proposes a collision avoidance algorithm that ensures minimum separation between the vehicles considering multiple no-fly-zones. The proposed algorithm aims to provide a practical and efficient tactical ...
  • Unmanned aerial system concept design for rail yard monitoring 
    Kirenga, Alain; Lee, Hae-In; Zolotas, Argyrios (AIAA, 2023-01-19)
    Safety and security monitoring in large yard areas, typical in rail yard environments, is an important task and any trespassing or vandalizing incidents can cause significant disruptions to routine activities and possibly ...
