New control concepts of the natural absolute trackability, absolute stablewise elementwise tracking and natural absolute tracking control are introduced for MIMO systems with multiple unknown controller Lurie nonlinearities, unknown linear part and unknown external disturbances. The concepts are...

The paper deals with the robustness of fuzzy control. The complementary sensitivity function which in the case of the cancellation control corresponds to the desired closed-loop transfer function must be shaped in order to fulfil the basic equation of robust stability. With classical robust...

In this paper, a complete control architecture is proposed for the voltage conditioning stage of a hybrid power generation system composed of a Stirling engine coupled with a supercapacitor. Such a solar energy-based generation system aims at providing electricity to off-grid regions. The...

This paper describes new software called NLSoft, developed for the design of nonlinear controllers based on the well-known feedback linearization technique. NLSoft is a software package containing several symbolic manipulation modules, which includes differential geometric tools for the design...

This paper proposes a new nonlinear control of three-phase three-level neutral point clamped (NPC) boost rectifier operating under severe disturbances. The nonlinear control strategy is employed to take into account the essential nonlinearities of the system and it totally differ from the common...

A general definition of synchronization is given, capturing features of both self-synchronized systems and systems synchronized by means of external control. The definition is exemplified by a number of special cases, including frequency or Hugenii synchronization. A new solution to the...

A neural network-based robust adaptive control design scheme is developed for a class of nonlinear systems represented by input–output models with an unknown nonlinear function and unmodeled dynamics. By on-line approximating the unknown nonlinear functions and unmodeled dynamics by radial...

The problem of designing a nonlinear feedback control scheme for variable speed wind turbines, without wind speed measurements, in below rated wind conditions was addressed. The objective is to operate the wind turbines in order to have maximum wind power extraction while also the mechanical...

After investigating the effect of the frequency of an external electrical stimulation on the chaotic dynamics of a single FitzHugh–Nagumo (FHN) neuron, this paper derives both a sufficient and a necessary condition of the coupling coefficient for self-synchronization of two interacting FHN...

In this paper, we propose a new deterministic global optimization method for solving nonlinear optimal control problems in which the constraint conditions of differential equations and the performance index are expressed as polynomials of the state and control functions. The nonlinear optimal...
