This paper presents a blind identification algorithm for non-minimum phase single-input single-output (SISO) plants using an over-sampling technique with each input symbol lasting for several sampling periods. First, an SISO autoregressive moving average (ARMA) plant is converted into its associated single-input multi-output (SIMO) system by holding the system input and over-sampling the system...

A new blind deconvolution method is proposed for recovering an unknown source signal, which is observed through two unknown channels characterized by non-minimum phase impulse response filters. Conventional methods cannot estimate the nonminimum phase parts. Our method is based on computing the eigenvector corresponding to the smallest eigenvalue of the input correlation matrix and using a cost...

The paper describes the use of the state space and the natural gradient for the demixing of sources mixed in a non-minimum phase convolutive environment. Non-minimum phase implies that some or all of the zeros of the mixing environment lie outside the unit circle, and as such the theoretical inverse or the requisite demixing system becomes unstable due to the presence of poles outside the unit ...

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...
