In industrial processing, workpiece quality and processing time have recently become important issues. To improve the machining accuracy reduce cutting time, feed rate will a significant impact. Therefore, how to plan dynamic is very important. this study, fuzzy control system for scheduling based on curvature variation proposed. The proposed implemented in actual cutting, verify data an optica...

An adaptive control system with a first-order plant and the so-called cr-modification adaptation law is analyzed in the case of periodic disturbance or reference input. The local bifurcations of the low-period solutions are numerically detected by means of a continuation method, and the different modes of behavior are classified as well as the transitions among them. As predicted by the theory,...

In this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. The objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. Successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...

The problem of Window Flow Controlled (WFC) systems has been analysed successfully in Deterministic Network Calculus (DNC). While many results of DNC have been carried over to its stochastic extension, the problem of WFC systems has not been solved so far. This paper presents the first approach to analyse WFC in the context of Stochastic Network Calculus (SNC) for a general service inside the f...

Fuzzy transform is a method which belongs to fuzzy approximation models. Its fundamentals are studied from different points of view. This approach allows to inherit results from different areas which are closely related to this method. Basically, it is shown to be a powerful approximation tool preserving features typical for fuzzy models. It is an appropriate tool for further numerical methods....

The topic of this paper is optimal input signal design for identification of interconnected/networked dynamic systems. We consider the case when it is only possible to design some of the input signals, while the rest of the inputs are only measurable. This is most common in industrial applications, where external excitation can only be applied to some subsystems. One example is feed-forward con...

The minimization control problem of quadratic functionals for the class of affine nonlinear systems with the hypothesis of nilpotent associated Lie algebra is analyzed. The optimal control corresponding to the first-, second-, and third-order nilpotent operators is determined. In this paper, we have considered the minimum fuel problem for the multi-input nilpotent control and for a scalar input...
