In this paper we study the problem of tracking a reference signal from the H" point, of view. As opposed to general Woo problems, whcrc only suboptimal solutions are obtained, wc show that for both the full information arid measurement, feedback tracking problems the H""-optimal solutions can be explicitly found. The results also indicate an interesting dichotomy between minimum phase and non-m...

-There has been a great deal of excitement recently over the development of a theory for explicitly linearizing the input-output response of a nonlinear system using state feedback. One shortcoming of this theory is the inability to deal with non-minimum phase nonlinear systems. Highly maneuverable jet aircraft, such as the V/STOL Harrier, belong to an important class of a slightly non-minimum ...

Quadruple tank process is a Multi-Input-Multi-Output process exhibiting both minimum phase and non-minimum phase behaviour. In this research, an attempt has been made to mathematically model and design a fuzzy controllerr for the non-minimum phase of Quadruple Tank Process. Both servo and regulatory responses are obtained for the proposed controller.

in this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. in addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. in the proposed control metho...

We suggest that the fluctuations of strange hadron multiplicity could be sensitive to the equation of state of strongly interacting matter created at the early stage of high energy nucleus– nucleus collisions. They may serve as an important tool in the study of the deconfinement phase transition. We predict, within the statistical model of the early stage, that the ratio of properly filtered st...

Control engineers have been aware of non-minimum phase systems showing either undershoot or time-delay characteristics for some considerable time (Linoya & Altpeter, 1962; Mita & Yoshida, 1981; Vidyasagar, 1986; Waller & Nygardas, 1975). A number of researchers that addressed this problem from a predictive control point of view mainly followed one of two approaches: a classical (non-optimal) pr...

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 ...
