On pole-placement controllers for linear time-delay systems with commensurate point delays
(Hindawi Publishing Corporation, 2005)
We investigate the exact and approximate spectrum assignment properties associated with realizable output-feedback pole-placement-type controllers for single-input single-output linear time-invariant time-delay systems ...
Fractional hold circuits versus positive realness of discrete transfer functions
(Hindawi Publishing Corporation, 2005)
The appropriate use of fractional-order holds(beta-FROH) of correcting gains beta is an element of[- 1,1] as an alternative to the classical zero- and first-order holds(ZOHs, FOHs) is discussed related to the positive ...
Robustly stable multiestimation scheme for adaptive control and identification with model reduction issues
(Hindawi Publishing Corporation, 2005)
A discrete pole-placement-based and multiestimation-based adaptive control scheme involving a relative adaptation dead zone is presented for a plant with known poles and unknown zeros., The basic usefulness of the proposed ...
Adaptive control of single-input single-output hybrid systems possessing interacting discrete- and continuous-time dynamics
(Hindawi Publishing Corporation, 2005)
This paper deals with the problem of synthesizing a robust adaptive controller for a specific class of single-input single-output (SISO) time-invariant hybrid controlled object (plant) which can operate under bounded ...
