Development of a cascade controller structure including adaptive backstepping for a nonlinear hydraulic-mechanical system is considered in this paper where a dynamic friction (LuGre) model is included to obtain the necessary accuracy. The paper compares the performance of two variants of an adaptive backstepping tracking controller with earlier results. The new control architecture is analysed ...

In this paper we propose a multifractal traffic model that is based on a multiplicative cascade presenting specific multiplier distributions in each cascade stage. In the proposed model, the multipliers are obtained through the estimate of their probability densities found in real network traffic by using Kernel and Acceptance/Rejection methods. Statistical analysis and queueing behavior study ...

The paper presents common cascade control architecture where specific kind of redundancy could be considered. There are different approaches how to increase the reliability of networked control systems. Common approach uses redundant components in control system i.e. passive or active redundancy. We deal with quasi-redundant subsystems (shared redundancy) which could be very useful when critica...

A non-cascade structure with a simple parameter adjustment method and satisfying dynamic performance is investigated so as to address the problem of complicated typical cascade control system permanent magnet synchronous motor (PMSM) system. However, current cannot work within limited value under this structure, which poses risk circuit safety. To end, fast non-singular sliding mode (FNTSM) spe...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system that inflammation, demyelination, oligodendrocyte loss, gliosis, axonal injury and neurodegeneration are the main histopathological hallmarks of the disease. Although MS was classically thought as a demyelinating disease, but axonal injury occurs commonly in acute inflammatory lesions. In MS mi...

This paper is concerned with the H∞ control problem for a class of non-minimum phase cascade switched nonlinear systems. The system under consideration is composed of two cascade-connected parts which are also switched systems. Sufficient conditions under which the H∞ control problem is solvable under an arbitrary switching law are presented. The Common Lyapunov function and the switched state ...

Aiming at the problems of large delay and poor anti-disturbance ability in outlet temperature control system heat exchanger to optimize accuracy improve performance, this paper proposes a scheme combining predictive functional with proportional-integral-derivative control. Using incremental algorithm optimization objective function algorithm, model structure is established. The feedforward comp...
