“…Serial is used as nonsinusoidal voltage compensator, shunt APF is used as non-sinusoidal current compensator. The relationship between the functionality of serial active filters, shunt active filters and hybrid filters, their topology, and implementation features of the control system are considered in [1][2][3][4][5][6][7]. Systems with connection of APF in parallel with load are characterized by big opportunities of attenuation of the higher harmonics of current of a network, and as a consequence, good filtering characteristics [2,6].…”

“…Compensation of reactive loads can be attributed to the most effective energy-saving technologies in electrical networks of consumers and power systems. Also, the increased requirements for the quality of electricity consumed from the supply network led to the emergence of a number of scientific works aimed at developing devices and methods to reduce the influence of electricity consumers on the supply network [1][2][3][4][5][6][7]. These devices include reactive power compensators and active power filters (APF).…”

The expediency of using a power active filter in the mode of reactive power compensation of the supply network for the powerful sounding pulses shaper power supply system of the Institute of ionosphere NAS and MES of Ukraine is shown. An analysis of the literature has been carried out, which shows the effectiveness of solving the problem of reactive power compensation, filtering higher harmonics of the power supply network using active filtering of higher harmonics of current or voltage using an additional energy source to obtain a compensating signal in the form of current or voltage. The choice of the power circuit for constructing a power active filter has been made. A voltage inverter on IGBT transistors is used as a power active filter. The basic principles of operation of the power active filter control system are described, which are based on the p-q theory of power and provide for the calculation of instantaneous values of the task currents for each phase of a three-phase power supply system. The work of the Matlab-model of the power supply system of the shaper is shown, the oscillograms of the main energy characteristics of the shaper are given. As a result of using a power active filter, the current of the supply network becomes close to sinusoidal, and the power factor tends to 1. A positive effect on the efficiency of the shaper when the power active filter is included in the supply network is noted, which is due to the efficiency of compensation of the reactive power consumed by the shaper from the supply network. The simulation results are presented, in particular, graphs of reactive power change at the point of connecting the power active filter to the supply network, at different levels of reactive power consumption by the shaper. The results obtained confirmed the possibility of using a power active filter in the mode of reactive power compensation of the supply network when solving the problems of improving the electromagnetic compatibility of powerful sounding pulses shapers with the supply network, reducing losses and increasing the reliability of the shapers.

In this paper enhanced control strategies for standalone microgrids based on solar photovoltaic systems (SVPAs) and diesel engine driven fixed speed synchronous generators, are presented. Single-phase d-q theory-based sliding mode controller for voltage source converter voltage source converter (VSC) is employed to mitigate harmonics, balance diesel generator (DG) current, and to inject the generated power by SVPA into local grid. To achieve fast dynamic response with zero steady-state error during transition, sliding mode controller for inner control loop is employed. To achieve maximum power point tracking (MPPT) from SVPA without using any MPPT method, a DC-DC buck boost converter supported by battery storage system is controlled using a new control strategy based on sliding mode control with boundary layer. In addition, modeling and detailed stability analysis are performed. The performance of the developed control strategies, are validate by simulation using MATLAB/Simulink and in real-time using hardware prototype.

“…Variable structure controllers (like sliding mode controllers) are powerful robust control methods which have effective performance in practical engineering problems (Hu, Wang, Gao, & Stergioulas, 2012;Hu, Wang, & Gao, 2011). The basis of this control method is the design of appropriate sliding surfaces (to achieve the control objectives) and switching control laws so that the system trajectories reach to the desired sliding surface in finite time and stay on it for all future times (Boum, Djidjio Keubeng, & Bitjoka, 2017;Chenarani & Binazadeh, 2017;Su, Liu, Shi, & Song, 2018). Eksin, Tokat, Güzelkaya, and Söylemez (2003) proposed a time-varying sliding surfaces in order to minimize the settling time for second-order systems.…”

In this paper, a new robust suboptimal controller is designed to stabilize a class of uncertain nonlinear time-varying systems with slowly varying parameters. In the design procedure of the proposed controller, first a suboptimal control law is designed for the nominal system based on considering a given cost function and an appropriate Slowly Varying Control Lyapunov Function (SVCLF). After that, a robustifying term is added to the nominal controller in order to vanish the effects of model uncertainties and/or external disturbances in a finite time. For this purpose, a special sliding surface, which is a combination of terminal and integral sliding surfaces, is used. This surface has the advantages of both of terminal and integral surfaces. Due to the structure of this surface, the actual trajectories track the desired one in the finite time. The other innovation of the proposed approach is accessing a chattering-free Controller. Finally, in order to confirm the applicability of the proposed controller and verify the theoretical results, it is applied on a practical benchmark system (a time-varying inertia pendulum). Computer simulations show the efficiency of the proposed controller. ARTICLE HISTORY
