Cascade control configurations offer interesting possibilities to improve the control of processes. However, the tuning of cascade controllers can be quite complex, which hampers a wider spread of applications. Using an on-line pattern recognition approach and fuzzy inferencing it is possible to...

In this paper, we study perturbed Chua’s system. First, we study the stability of equilibrium points of perturbed Chua’s system. Then, we control the chaotic behavior of perturbed Chua’s system to its equilibrium points using linear feedback control and adaptive control methods. Finally,...

We address the problem of control and synchronization of a class of uncertain chaotic systems. Our approach follows techniques of sliding mode control and adaptive estimation law. The adaptive algorithm is constructed based on the sliding mode control to ensure perfect tracking and...

Three-leg inverters for photovoltaic systems have many disadvantages, especially when the load is unbalanced. These disadvantages are, for example, small utilization of the DC link voltage, the dependency of the modulation factor of the load current and the superposition of a DC component with...

In recent times, sun tracking systems are being increasingly employed to enhance the efficiency of photovoltaic panels by constantly tracking the elevation and azimuth angles of the sun. In this paper, a novel adaptive digital signal processing and control algorithm is presented that optimizes...

In this paper we present two adaptive control formulations that explicitly include uncertainty in characterizing a facility's deterioration rate in the process of developing maintenance and repair policies. The formulations use condition information that stems from the operation of a facility to...

In this paper, an Internal Model Control (IMC) scheme is incorporated in production inventory control systems in a complete supply chain. This control scheme presents a good target inventory tracking under the perfect knowledge of the system. Furthermore, the inventory tracking and load...

One of the most important problems of terminal control reduction problem is considered and solved. On the base of spinor representation of spatial rotation group, the control law functions are obtained. A mathematical model of reduction process is constructed. The results can be used for...

Solution of breaking problem of moving mechanical object is discussed. Five boundary values are used for the problem. Mathematical model of the process has been obtained. Also all dynamic functions and characteristics are represented. They shoe the accuracy of terminal positioning of deceleration.

Among the problems of Adaptive Terminal Control, one of the most important is the problem of control of acceleration process of moving objects. Two cases are discussed: Control with arbitrary terminal acceleration and control with certain value of terminal acceleration. The control law functions...
