“…Since by using this design pattern the program execution is no longer linear, the part of the code which will be executed depends on the inputs from HMI or sensors (asynchronous discrete-time events), or the results of the current execution. Traditionally, FPGA design were limited to hardware designers, but using LabVIEW FPGA control systems designers are supported with enough "system-level" abstraction in order to deploy their designs to FPGAs [10]. Thus, a combination of an FPGA and RT software to control the sequences of the sowing cycle was developed in the form of a state machine, allowing to extend its functionality without restrictions.…”

“…Generally, FPGA takes the benefits of the high execution speeds on FPGA targets but the software design requires minimisation of the resource consumption. Even with trends like multi-core, a processor-based solution will never get the parallelism offered by FPGAs [10]. The complexity and the increasing number of questions and hypothesis within experimental praxis which are expected to be answered or tested require an ever increasing amount of field data.…”

A novel precision plot seeder for medicinal and aromatic plants was designed and built. Based on the system design-oriented development as well as the implemented state-of-the-art hardware and software solutions, it was possible to identify the problems in the early phase of the design process, to create multiple design variants, to overcome the lack of cross-disciplinary knowledge and consequently achieve savings in associated labour and material costs. The electrification should provide more accurate seed placement and continuous regulation of seed rates and row length for each row, as well as the option to generate detailed documentation about the sowing process. KeywordsPrecision plot seeder, experimental practice, digital prototyping, system based designs IntroductionThe Food and Agriculture Organisation of the United Nations (FAO) projected that if current patterns in food consumption will persist, 60 percent more food will need to be produced to meet the needs of the growing earth population that is expected to top the nine billion mark in 2050. Changes towards more sustainable production are required including investments in research, development and dissemination of the technologies and information in order to improve efficiency and reduce waste and pollution. The increase of the resource use efficiency, cutting the use of fossil fuels and reducing direct environmental degradation are some of the important components which can improve sustainable development in the agricultural sector [1]. Further development of methods and techniques in the field of experimental practice can positively affect the process of achieving these requirements.The sowing equipment used in experimental practice require high degree of modularity to use it for as many crop species as possible and to be able to assess as many issues as possible within the experimental research with respect to the optimisation of the seeding process. A prerequisite is an even distribution of the defined amount of seeds over the predetermined length of a trial plot. Depending on the explicit research question, the distances between the rows, which number can vary, need to be exactly retained. Above all an accurate and steady sowing depth, an important parameter for the optimum germination [2, 3], needs to be maintained for each row on the entire plot length and ideally should be carried out automatically. The mechanisation within the experimental praxis started in second half of the twentieth century and the backgrounds and requirements for sowing equipment have been listed and evaluated by Kemp [4], Cameron et al. [5] and Hergert [6]. In that time, considerable savings in time and labour were anticipated from the newly developed machinery in regarding the manual sowing.Medicinal and aromatic crops belong to high value specialty crops and are often established on fields by sowing. The species vary in grain size, thousand seed weight, required seed rates, shape and surface textures, strength of the bran and composition of the grain sizes. The...

“…Other specific implementations of these controllers can be found in applications such as automotives [ 41 ] or education [ 42 ]. The increasing capabilities of the FPGAs have opened a new line of research investigating methodologies for scaling intelligent controllers or architectures into embedded systems based on FPGAs [ 43 ]. This can be accomplished by the implementation of neural networks [ 44 ].…”

The current trend in the evolution of sensor systems seeks ways to provide more accuracy and resolution, while at the same time decreasing the size and power consumption. The use of Field Programmable Gate Arrays (FPGAs) provides specific reprogrammable hardware technology that can be properly exploited to obtain a reconfigurable sensor system. This adaptation capability enables the implementation of complex applications using the partial reconfigurability at a very low-power consumption. For highly demanding tasks FPGAs have been favored due to the high efficiency provided by their architectural flexibility (parallelism, on-chip memory, etc.), reconfigurability and superb performance in the development of algorithms. FPGAs have improved the performance of sensor systems and have triggered a clear increase in their use in new fields of application. A new generation of smarter, reconfigurable and lower power consumption sensors is being developed in Spain based on FPGAs. In this paper, a review of these developments is presented, describing as well the FPGA technologies employed by the different research groups and providing an overview of future research within this field.

“…(2) Microcontrollers could be used to implement hardware circuitry, but it consumes areas of design with more complexity, (3) Field programmable gate arrays (FPGA )is considered the best solution for hardware implementation [42][43][44][45][46][47][48], in case of high flexibility, reprogrammable, rising integration scale, and large scale integration [49,51] . Novel advanced features embedded in this device bring a new scenario to be used for modern applications [52].…”

Tremendous studies have been proposed to optimize PI controller based Genetic Algorithm (GA) to improve the speed performance of DC motor commonly required in robotic applications. In PID controller, there are very few studies to overcome the drawbacks of classical GA, besides little pay attention to improving the speed performance of a DC motor to be measured in the microsecond unit. The main target is to maximize reduction step response characteristics, by proposing to design and fabricate a high speed proportional integral controller system (HSPICS). The primary methodology includes three sub methodologies using several new techniques and procedures to achieve three objectives. Firstly, to propose an improved genetic algorithm (IGA) to enhance the performance for better searching constraints for PI controller. Secondly, generate VHDL based Simulink model without needing expensive software. Finally, integrate the proposed controller-based on FPGA_SoC using Embedded Coder and FPGA in the loop (FIL) techniques to run the design based model. To show the effectiveness of the proposal, it was used three different DC motors. Simulation results show that the proposed controller achieves much higher reduction step response ratios (RSRR) compared with classical GA and PSO, further shortened step response characteristics to be measured in the microsecond unit. Analyzing the performance demonstrates that the RSRR has been enhanced for motors 1, 2, and 3 by 8, 9, and 35 times over classical GA, and 3, 3, and 10 over PSO, respectively. The comparison response time results between simulation and experimental for the studied motors show that the steady state time ratios (SST) were minimized significantly.
