The input output decoupling problem for discrete time nonlinear systems by static output feedback is studied in this paper The discrete time nonlinear system is described either by state equations or by high order input output di erence equations NARMA model In both cases the necessary and su cient conditions are given for the solution of the problem Copyright c IFA C

In this paper, we construct feedback controllers, explicitly parameterized in a single parameter e, that solve the well-known H = almost disturbance decoupling problem with measurement feedback and with internal stability (H = -ADDPMS) for discrete-time linear systems. In particular, we explicitly construct parameterized solutions for the following three cases: the full state feedback, the full...

Partial disturbance decoupling problems are equivalent to zeroing the first, say k Markov parameters of the closed-loop system between the disturbance and controlled output. One might consider this problem when it is not possible to zero all the Markov parameters which is known as exact disturbance decoupling. Structured transfer matrix systems are linear systems given by transfer matrices of w...

Payload-specific vibration control may be suitable for a particular task but lacks generality and transferability required adapting to the various payload. Self-decoupling robust are crucial problem achieve payload-agnostic control. However, there problems still unsolved. In this article, we present maglev isolation platform (MVIP), which aims attenuate in under dynamic environment. Since effor...

Abstract Single-phase inverters have a wide range of applications in many fields, but there are inherent double frequency problems, and fluctuations can easily cause system instability. This paper proposes mid-point common-mode injection power decoupling circuit. The advantage this topology is that no additional switching devices only the original DC side support capacitors filter H-bridge inve...

A spin-wave theory of short-range order in the square lattice Heisenberg antiferromagnet is formulated. With growing temperature from T = 0 a gapless mode is shown to arise simultaneously with opening a gap in the conventional spin-wave mode. The spectral intensity is redistributed from the latter mode to the former. For low temperatures the theory reproduces results of the modified spin-wave t...

Simultaneous switching noise (SSN) is a major cause of power integrity (PI) degradation that causes circuits to become unstable and experience errors. As modern ICs operate at higher speeds with higher density and lower voltages, SSN has become a serious issue that must be addressed to ensure system stability during the short riseand fall-times of the logic transient states. Most traditional de...
