The currently used hardware validation architectures for Application Specific Integrated Circuits intended for automotive Engine Control Unit development are reviewed and a new architecture is proposed. An alternative to hardware validation by different simulation architectures is proposed and analyzed.
This paper concerns with the design and implementation of a microcontroller based PID controller for the purpose of controlling PMDC motor speed. The design had been done using MATLAB and Simulink and the system then simulated using Proteus, in addition to a practical physical system. The controller was implemented on an Arduino Uno board to control the speed of the motor at a desired value with the...
In this work, a structure of the controller for registering passenger flow (CRPF) of public transport for the “smart” city system was designed. Controller operation based on the use of cheap mini-computer Raspberry Pi. Structural model of the controller was built with using the method of simulation by Petri nets. Software and hardware for controller was developed, the particular implementation of...
This paper basically provides a real time model of a low cost wheel chair based on the guiding movement of the retina, for the persons disabled with quadriplegia. This model is expected to benefit the poor paralyzed people as it provides a simplified low cost model of the wheel chair. The model is realized through matlab in serial communication with the special purpose microcontroller IC manufactured...
This paper demonstrates the validation and performance testing of a decoupled controller for a single phase single stage rooftop PV by its hardware in loop (HIL) implementation. The designed controller was programmed in a digital signal controller. The rest of the system placed in real time simulator i.e. OP5600 HIL box from OPAL-RT. By the help of asynchronous communication between the plant in HIL...
Most electrical and mechanical engineering curricula include courses in controls and mechatronics, with mechanical engineering curricula also including system dynamics and vibrations courses. The laboratory component for these courses is often limited and involves using a limited number of experimental setups. At many institutions, the laboratories associated with these courses are not taken in the...
The biggest problems arise at elaborating hardware models of FitzHugh-Nagumo neuron is related with implemantation of nonlinear part of the system. It is really difficult to realize such nonlinear part using analogue circuits, however it can be easily realized using microcontroller. In the article the elaborated microcontroller based hardware model of FitzHugh-Nagumo neuron was considered. The article...
Particle Swarm Optimization (PSO) algorithms have been proposed to solve engineering problems that require to find an optimal point of operation. However, the PSO algorithm suffers from premature convergence and high elapsed time when solving multimodal and large scale engineering problems. This problem becomes an evident drawback for embedded applications in which the microcontrollers often operates...
This paper presents how model-implemented fault injection can be utilized to simulate the effect of hardware-related faults in embedded systems. A fault injection environment has been developed to enable comparison of experiments at model level and hardware level using Simulink and an Infineon microcontroller, respectively. Experiments at model level, leading to safety requirement violations, are...
Till date, sensor network research has assumed that the cost of transmitting a sensor reading over the network is much higher than the cost of sampling a sensor. However, this assumption is no longer always valid, due to availability of new generation sensor platform hardware, which utilizes industry standard mesh-networking protocols such as ZigBee on top of relatively high-speed, yet low-power wireless...
In this work, hardware and software issues of building a control system for axial magnetic bearings are considered. The third generation of magnetic bearings requires self-tuning and self-calibration. These techniques should be complemented by an option of a controller switch in operational processes. An implementation of a bumpless method is discussed for cases that solve the problem of system instability...
This paper discuses hydrophone calibration for generation of artificial Ultra High Energy (UHE) neutrino-induced pulses. Signal processing techniques are applied to hydrophone modelling. A bipolar acoustic generation module is built using PIC microcontrollers for processing and control. The NI-USB6211 commercial module is used for comparison. The modelling is compared to experimental data generated...
The research work presented in this paper is focused on the modelling of matrix converter systems, targeting field programmable gate arrays (FPGA) for the rapid prototyping of the associated digital electronic controllers. The novel approach is based on a high level description language, Handel-C, used within a modelling environment created by Celoxica Ltd., called DK5. The matrix converter system...
We develop several hardware and software simulation blocks for the TinyOS-2 (TOSSIM-T2) simulator. The choice of simulated hardware platform is the popular MICA2 mote. While the hardware simulation elements comprise of radio and external flash memory, the software blocks include an environment noise model, packet delivery model and an energy estimator block for the complete system. The hardware radio...
