Can arise from fast and slow responses of opposite sign: G(s) = 1 s + 1 − 2 s + 5 = 3 − s (s + 1)(s + 5) .

This paper presents an Internal Model Control (IMC) structure designed for a class of continuous linear underactuated systems. The study treats the case of Minimum Phase (MP) systems and those whose zero dynamics are not necessarily stable. The proposed IMC structure is based on a specific controller which is obtained by the realization of an approximate inverse of the model plant. It is shown ...

In this paper, we develop a nonlinear controller to achieve causal output tracking for a non-minimum phase vertical take-off and landing (VTOL) aircraft without velocity measurements. Due to the presence of disturbances, auxiliary control inputs are introduced in the state observer to attenuate their effects. By decomposing the original system into one minimum phase and one non-minimum phase su...

A piezoelectric tube is shown to have linear, but non-minimum phase dynamics. The main impediment to the actuation of this piezoelectric tube is the presence of a low-frequency resonant mode which causes mechanical vibrations. A physical-model-based control method is extended to non-minimum phase systems in general and successfully applied to damp the resonant mode; leading to a vibration-free ...

In this paper we propose a family of algorithms based on 3 and 4 order cumulants for blind single-input single-output (SISO) Non-Minimum Phase (NMP) Finite Impulse Response (FIR) channel estimation driven by non-Gaussian signal. The input signal represents the signal used in 10GBASE-T (or IEEE 802.3an-2006) as a Tomlinson-Harashima Precoded (THP) version of random Pulse-Amplitude Modulation wit...
