About the position

We have a vacancy for a PhD at Departement of marine technology.

We have a vacancy for a PhD position on Resilient hybrid motion control of autonomous marine vessels with Sn formulation of orientation at NTNU’s Centre for Autonomous Marine Operations and Systems (NTNU AMOS), Department of Marine Technology. The PhD candidate will work in a specialist control engineering environment at NTNU AMOS and the CCDC group at UCSB.

The PhD position aims for the development of novel methods for controlling and observing motions of autonomous vessels, especially orientations, with properties of global stability, robustness to perturbations, and resilience to deliberate disturbances. The PhD study will in particular study hybrid control methods with Sn formulations of orientations to generate control and observer algorithms that achieve strong formal stability and robustness properties at the same time as being practical for computer implementations. The study will further look into how to construct outer guidance and mission planning loops to autonomously optimize operations in a given marine environment. This may be combined with a higher-level learning layer that, given sensed information of the vessel and environment, is capable of generating internal models of the operating environment as input to the mission planning.

The position reports to the supervising professor.

Job description

  • Formulate planar and spherical orientations represented by vectors on the unit sphere (Sn).
  • Develop robust hybrid feedbacks to control orientations of vessels on Sn, with global stability properties.
  • Apply the hybrid feedback control laws to dynamic positioning, heading control, velocity vector control, and path-following control of autonomous ships with robust compensations of current loads.
  • Study the dual problem of observer design for vessel motions using Sn-formulations of orientation.
  • Study the integration of a higher-level guidance loop to provide setpoints to the low level hybrid motion controls in order to perform operation tasks such as stationkeeping or path-following. Characterize stability and robustness issues in this integration, and develop compensating mechanisms.
  • Study and propose an integration of a mission planning layer with the guidance loop, in order to autonomously generate missions according to a high-level mission objective.

Qualification requirements

PhD candidate:

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in [subject area] or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant

Other qualifications

  • We seek a highly motivated candidate with a MSc degree preferably in Marine Cybernetics (with a Marine Technology and hydrodynamics basis), or alternatively in Engineering Cybernetics or Control Engineering with an application basis on marine systems and hydrodynamics.
  • Master students graduating summer 2019 can apply. Master students graduating by the end of June 2020 may apply for admission as integrated MSc and PhD.
  • Relevant industry experience is an advantage, especially within marine control systems and hydrodynamics.
  • Academic results, publications, relevant specialization, work or research experience, personal qualifications, and motivations for making an impact on future autonomous marine systems will be considered when evaluating the applicants.
  • Excellent English skills, written and spoken, are required. Applicants from non-English speaking countries outside Europe must present an official language test report. The acceptable tests are TOEFL, IELTS, and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:
    • TOEFL: 600 / writing 4.5 (paper-based test), 92 / writing 22 (internet-based tes
    • IELTS: 6.5, with no section lower than 5.5 (only Academic
    • IELTS test accepted)CAE/CPE: grade B or A.

Our research has civilian objectives. However, equipment restricted by export licenses and ITAR (International Traffic in Arms Regulations) is being used in the research areas listed above. Applicants that are citizens of Norway, Australia, Japan, New Zealand, Switzerland, EU or NATO countries are eligible. Other applicants are required to provide evidence of eligibility to use such equipment for their application to be considered in their application.

Personal characteristics

  • Courage
  • Generous
  • Thourough
  • Effective
  • Innovative and open minded
  • High integrity

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement
