  • Adaptive control for nonlinearly parameterized uncertainties in robot manipulators 
    Hung N V; Hoang Tuan; Narikiyo T; Apkarian Pierre (IEEE-Inst Electrical Electronics Engineers Inc, 2008)
    In this brief, a new adaptive control framework to compensate for uncertain nonlinear parameters in robot manipulators is developed. The designed adaptive controllers possess a linear parameter structure, guarantee global ...
  • Gain-scheduled filtering for time-varying discrete systems 
    Hoang Nguyen; Hoang Tuan; Apkarian Pierre; Hosoe Shigeyuki (IEEE-Inst Electrical Electronics Engineers Inc, 2004)
    This paper deals with the design of gain-scheduled filters, whose state-space realization depends on real-time parameters of plants. Similar to well-recognized advantages of gain-scheduled controllers in control theory, ...
  • Low-order IIR filter, bank design 
    Hoang Tuan; Son T; Apkarian Pierre; Nguyen Tuan (IEEE-Inst Electrical Electronics Engineers Inc, 2005)
    The advantage of infinite-impulse response (IIR) filters over finite-impulse response (FIR) ones is that the former require a much lower order (much fewer multipliers and adders) to obtain the desired response specifications. ...
  • A Lyapunov Variable-Free KYP Lemma for SISO Continuous Systems 
    Hoang Hung; Hoang Tuan; Apkarian Pierre (IEEE-Inst Electrical Electronics Engineers Inc, 2008)
    This technical note proposes a novel frequency-selective Kalman-Yakubovich-Popov (FS-KYP) lemma for analysis of single-input single-output (SISO) continuous systems. In contrast to existing approaches, the proposed method ...
  • New fuzzy control model and dynamic output feed back parallel distributed compensation 
    Hoang Tuan; Apkarian Pierre; Narikiyo T; Kanota M (IEEE-Inst Electrical Electronics Engineers Inc, 2004)
    A new fuzzy modeling based on fuzzy linear fractional transformations model is introduced. This new representation is shown to be a flexible tool for handling complicated nonlinear models. Particularly, the new fuzzy model ...
  • Robust filtering for discrete nonlinear fractional transformation systems 
    Hoang Nguyen; Hoang Tuan; Apkarian Pierre; Hosoe Shigeyuki (IEEE-Inst Electrical Electronics Engineers Inc, 2004)
    In this brief, we consider robust filtering problems for uncertain discrete-time systems. The uncertain plants under consideration possess nonlinear fractional transformation (NFT) representations which are a generalization ...
  • A spectral quadratic-SDP method with applications to fixed-order H-2 and H-infinity synthesis 
    Apkarian Pierre; Noll D; Thevenet J; Hoang Tuan (Lavoisier, 2004)
    In this paper, we discuss a spectral quadratic semi,finite programming (SDP) method for the iterative de resolution of fixed-order H-2 and H-infinity design problems. These problems can be cast as regular SDP programs with ...
