This study presents an automatic glottal inverse filtering (GIF) technique based on separating the effect of the glottal main excitation from the impulse response of the vocal tract. The proposed method is based on a non-negative matrix factorization (NMF) based decomposition of an ultra short-term spectrogram of the analyzed signal. Unlike other state-of-theart GIF techniques, the proposed met...

This paper contains results on the design of optimum equalizers to eliminate intersymbol interference in linear non-minimum phase channels conveying binary signals. The optimization is with respect to an open eye condition with a given delay. For causal stable channels with non-minimum phase zeros, we argue that this problem requires only the consideration of the FIR modified channel that has a...

This paper argues that the 'optimization along trajectories' formulation of the distal learning approach [1] doesn't work on non-minimum phase dynamical plants [2] and the 'local optimization' one doesn't work on plants with variable or badlyestimated time-delay. It then proposes a modification of the procedure and illustrates improvements on the control of a simulated irrigation canal. This pa...

Nonminimum phase difficulties prevent the use of input-output feedback linearization. To avoid this problem, earlier work proposed the use of synthetic outputs with the view of placing zeros in prescribed locations under a condition of static equivalence. The objective here is also to introduce a synthetic output. However this is defined through the use of dynamic perturbations aimed at yieldin...

In the present work, implementation of continuous-time high frequency periodic controller is done for stabilization of non-minimum phase system having both right half plane (RHP) pole and zero. This work considers nonminimum phase cart-inverted pendulum system as a test bench. The robustness property of the periodic controller is compared with that of a linear quadratic regulator (LQR) and slid...

Immersive audio systems are being envisioned for applications that include teleconferencing and telepresence; augmented and virtual reality for manufacturing and entertainment; air traffic control, pilot warning, and guidance systems; displays for the visually-impaired; distance learning; and professional sound and picture editing for television and film. The principal function of such systems ...

In this paper, we propose a framework for output tracking control of both minimum phase (MP) and non-minimum phase (NMP) discrete-time linear systems. Towards this end, we first address the problem of unknown state and input reconstruction of non-minimum phase systems. An unknown input observer (UIO) is designed that accurately reconstructs the minimum phase states of the system. The reconstruc...

The paper presents a new tracking control approach for a class of non-minimum phase linear systems. The proposed approach consists of two parts: trajectory planning and tracking controller design. The trajectory planning is solved as an optimization problem to improve the achievable transient performance under the fundamental constraints associated with perfect tracking of non-minimum phase sys...
