Research Highlights

  • Derived conditions for:
    • Unstructured decentralised fixed modes (UDFMs) to be quotient fixed modes (QFMs).
    • Decentralised fixed modes (DFMs) to be (not to be) QFMs in terms of transmission zeros (TZs).
    • DFMs that are distinct or repeated eigenvalues of LTI systems to be QFMs using new graph theoretic concepts.
    • Elimination of DFMs by sample data control.
    • Decentralised decomposition of LTI systems that guarantees existence of no DFM or QFM using system graph.
  • Designed a fully decentralised power system stabiliser using a novel graph approach to damp the power system inter-area oscillations.
  • Decentralised control design for power system voltage stability enhancement.   


Mohammad Abdolmaleki is a Ph.D. student at the department of Electrical and Electronic Engineering, The University of Melbourne. He holds an M.Sc. from Sharif University of Technology, Tehran and a B.Sc. from Iran University of Science and Technology, Tehran. He is currently working with Future Grid Research Center at the University of Melbourne.
