The design and physical implementation of a self-controlling dynamically reconfigurable system is described in detail. The reconfiguration control logic and target application execute in parallel within the same FPGA. In addition, the data required for each reconfiguration is generated on demand. A pattern-matching algorithm is used to investigate the viability of systems that exhibit self-cont...

This paper introduces JHDLBits, the integration of two prominent FPGA design tools: JHDL and JBits. JHDLBits offers the low-level access and control provided by JBits with the high-level structural circuit design of JHDL. Furthermore, the JHDLBits flow provides greater control of resource manipulation, placement, and routing, and gives researchers a “sandbox” to explore advanced interactions wi...

In this paper a novel, simple and reliable digital firing scheme has been implemented for speed control of three-phase induction motor using ac voltage controller. The system consists of three-phase supply connected to the three-phase induction motor via three triacs and its control circuit. The ac voltage controller has three modes of operation depending on the shape of supply current. The per...

CubeSat attitude control systems must be compact, fast, and accurate to achieve success in space missions with stringent control requirements. Nonlinear control strategies allow the creation of robust algorithms for orbit and attitude control, but can have higher processing requirements in operation. In addition, It is desirable to implement distribute components of a CubeSat control system acr...

Nowadays, FPGA devices are widely used to build control platforms in various fields of real time applications such as wireless telecommunications, image and signal processing, robotics and renewable energy systems. In grid-connected photovoltaic (PV) systems, an effective control strategy is needed for an efficiently use of solar energy as well as for energy supplies optimization. This paper pr...

This paper proposes a digital hardware control of Permanent Magnet Synchronous Motor (PMSM) using a SiC MOSFET inverter implemented in a FPGA (Field Programmable Gate Array) device. High frequency is required using a SiC MOSFET inverter to obtain high response and good stability for speed control systems. Not only the switching frequency of inverter, but also the control frequency is achieved u...

In this paper, we present a new contribution for the control of Wind-turbine energy systems, a nonlinear robust control of active and reactive power by the use of the Adaptative Backstepping approach based in double-fed asynchronous generator (DFIG-Generator). Initially, a control strategy of the MPPT for extraction of maximum power of the turbine generator is presented. Thereafter, a new contr...
