    • A Multiple-Reference Complex-Based Controller for Power Converters 

      Serra, Federico; Dòria Cerezo, Arnau; Bodson, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2021-12-01)
      Article
      Open Access
      A multiple-reference complex-based controller is proposed for three-phase power converters feeding nonlinear and unbalanced loads. The control scheme incorporates a stable multiple-complex coefficient filter with bandwidths ...
    • Complex pole placement control for a three-phase voltage source converter 

      Serra, Federico; Dòria Cerezo, Arnau; De Angelo, Cristian; Martín Fernández, L.L.; Bodson, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      In this work, a complex-valued controller for a three-phase VSC with an LC output filter is proposed. The system is first transformed into its complex representation with the consequent order reduction and simpler analysis. ...
    • Complex-based controller for a three-phase inverter with an LCL filter connected to unbalanced grids 

      Dòria Cerezo, Arnau; Martin Serra, Federico; Bodson, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2018-07-09)
      Article
      Open Access
      A new controller for a grid connected inverter with an LCL filter is proposed in this paper. The system is described by its complex representation and the controller is designed using the complex root locus method. The ...
    • Complex-valued sliding mode controllers for doubly-fed induction motors 

      Dòria Cerezo, Arnau; Hossain, Md Abid; Bodson, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2022-11-29)
      Article
      Open Access
      This article presents two algorithms to control the speed of doubly-fed induction motors. The controllers are designed using the complex-valued sliding mode methodology to track either the rotor or the stator current. An ...
    • Design of controllers for electrical power systems using a complex root locus method 

      Dòria Cerezo, Arnau; Bodson, Marc (2016-06-01)
      Article
      Open Access
      A large class of three-phase electrical power systems possess symmetry conditions that make it possible to describe their behavior using single-input single-output transfer functions with complex coefficients. In such ...
    • Root locus rules for polynomials with complex coefficients 

      Dòria Cerezo, Arnau; Bodson, Marc (2013)
      Conference report
      Restricted access - publisher's policy
      Applications were found recently where the analy- sis of dynamic systems with a special structure could be simp li- fied considerably by transforming them into equivalent syst ems having complex coefficients and half ...
    • Study of the stability of a direct stator current controller for a doubly fed induction machine using the complex hurwitz test 

      Dòria Cerezo, Arnau; Bodson, Marc; Batlle Arnau, Carles; Ortega, Romeo (2013-11)
      Article
      Restricted access - publisher's policy
      In this brief, a new control scheme is presented for the doubly fed induction machine (DFIM). The proposed control algorithm offers the advantages of proven stability and remarkable simplicity. In contrast to the classical ...
