Phase response reconstruction for non‐minimum phase systems using frequency‐domain magnitude values

Independent component analysis for nonminimum phase systems using H∞ filters

This paper proposes an independent component analysis (ICA) method using H∞ filters for nonminimum phase systems. In the basic ICA approach, the input signal is recovered by estimating the parameter of the inverse of the mixing system. If the system is nonminimum phase, the estimated parameter diverges due to the instability of the inverse. For this problem, a inverse filter is constructed base...

Blind Deconvolution in Nonminimum Phase Systems Using Cascade Structure

We introduce a novel cascade demixing structure for multichannel blind deconvolution in nonminimum phase systems. To simplify the learning process, we decompose the demixing model into a causal finite impulse response (FIR) filter and an anticausal scalar FIR filter. A permutable cascade structure is constructed by two subfilters. After discussing geometrical structure of FIR filter manifold, w...

Direct Adaptive Control of Nonminimum Phase Systems Using Integral Action

This paper presents a direct adaptive control scheme for nonminimum phase systems in which controller parameters are estimated from the recursive least-squares algorithm, and additional auxiliary parameters are obtained from the proposed polynomial identity. A local convergence is guaranteed without any extra condition. Integral action is incorporated into the adaptive controller to eliminate t...

Guidance of Nonlinear Nonminimum-Phase Dynamic Systems

A technique to achieve output tracking for nonminimum phase linear systems with non-hyperbolic and near non-hyperbolic internal dynamics is presented. This approach integrates stable inversion techniques, that achieve exact-tracking, with approximation techniques, that modify the internal dynamics to achieve desirable performance. Such modification of the internal dynamics is used (a) to remove...
