This paper present an optimal photovoltaic-hydrogen standalone power system using gray wolf optimizer technique. The system composed of photovoltaic generator and a hydrogen production system. Electrical power from solar conversion meets the user loads and the surplus used for water electrolysis to produce hydrogen. Control system is ensured via feed bucks control loops. MPP Tracking regulates with...
This paper provides comparative control study of PMSG wind turbine connected to DC load through a DC/DC converter in order to improve the impact on the power system and optimize the power production. The maximum power point tracking (MPPT) algorithms analyzed and compared are: A conventional proportional-integral controller (PI) and two based fuzzy logic controllers (Fuzzy-PI and Adaptive FLC-PI)...
A design of a feed-forward-based fractional-order model reference adaptive control (FO-MRAC) compensator using a modified MIT rule to control a DC-DC boost converter is presented in this work. As the plant is non-minimum phase, an implementation of the so-called parallel feed-forward configuration is required to make the plant satisfy ASPR (almost strictly positive real) conditions that in turn, allows...
This paper describes a PV system supplying a large scale interconnected grid. A PV array is connected to AC grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). Maximum Power Point Tracking (MPPT) is implemented in the boost converter by means of a Simulink model using sliding mode controller by switching the duty cycle of the boost converter. A three phase...
Designing of an effective and an efficient Fractional Order Proportional-Integral-Derivative (FOPID) controller, as a generalization of a conventional PID controller based on fractional order calculus, for an industrial control plant to obtain high-quality performances is of great theoretical and practical significance. This paper presents a new method for optimum tuning of practical FOPID controllers...
The paper presents a new multi-controllers approach with H∝ control applied to control a manipulator robot wrist (Staubli RX-90). A brief description of process and linear mathematical modeling of the process. Principle of multi-controllers approach of control is briefly presented. Our new proposals concerning the type of the controllers used in the multi-controller approach of control and which are...
