The method for controlling a DC-DC converter is proposed to ensures the high quality control at large fluctuations in load currents by using differential gain control coefficients and second derivative control. Various implementations of balancing the currents of a multiphase DC-DC converter are discussed, with a focus on achieving accurate current regulation without introducing additional delay in the controlsystem. Stochastic particle swarm optimization method is used to find optimal values of the PID controller parameters. An automatic constraint-handling in optimization are also discussed as relevant techniques in the field.

The paper describes the principles of the implementation of supervisors for discrete event systems, designed with the help of automatic theorem proving in the calculus of positively constructed formulas. The main advantage of the proposed approach is the ability to carry out complex evaluations of events on the base of the current state of the system. Computable predicates are also may be employed, definitions of which are based on the data coming from external sources. As an illustrative example a mobile robot movement in an unknown environment is considered.

The Hamiltonian theory for the collective longitudinally polarized colorless gluon excitations (plasmons) and for collective quark-antiquark excitations with abnormal relation between chirality and helicity (plasminos) in a high-temperature quark-gluon plasma (QGP) is developed. For this purpose, Zakharov’s formalism for constructing the wave theory in nonlinear media with dispersion is used. A generalization of the Poisson superbracket involving both commuting and anticommuting variables to the case of a continuous medium is performed and the corresponding Hamilton equations are presented. The canonical transformations including simultaneously both bosonic and fermionic degrees of freedom of the collective excitations in QGP are discussed and a complete system of the canonicity conditions for these transformations is written out. An explicit form of the effective fourth-order Hamiltonians describing the elastic scattering of plasmino off plasmino and plasmino off plasmon is found and the Boltzmann type kinetic equations describing the processes of elastic scattering are obtained. A detailed comparison of the effective amplitudes defined within the (pseudo)classical Hamiltonian theory, with the corresponding matrix elements calculated early in the framework of high-temperature quantum chromodynamics in the so-called hard thermal loop approximation is performed. This enables one to obtain, in particular, an explicit form of the vertex and coefficient functions in the effective amplitudes and in the canonical transformations, correspondingly, and also to define the validity of a purely pseudoclassical approach in the Hamiltonian description of the dynamics of a quark-gluon plasma. The problem of determining the higher-order coefficient functions in the canonical transformations of fermionic and bosonic normal variables is considered. With the help of the coefficient functions obtained, the totally symmetric effective amplitudes of the elastic scattering of plasmino of

The article offers the developed modifications of multiagent nature-inspired algorithms for finding the absolute extremum of multimodal objective functions. The proposed algorithms are based on hybridization with the quasi-Newton method for local descent at each iteration. Variants of genetic, biogeography, and particle swarm methods proposed by the authors are used for global search. We have performed the numerical comparison of implemented algorithms employing a representative set of multiextremal functions. The achieved research results confirm the efficiency of the proposed algorithms and the possibility of constructing computational schemes, which can be the foundation for effective methods for studying global search problems.
