The control algorithms and their software implementation play crucial role in real-time embedded systems reliability and safety. Field programmable gate arrays (FPGA) based hardware in the loop (HIL) is a relatively new technique used for development and testing of hard real-time complex systems. The system simulator implemented in FPGA provides real time reactions to control system actuations. The...
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...
This paper presents an integration of a low cost microcontroller with a power converter for controlling the output voltage. Here, it will benefit the UTHM final year student in order to apply what have been taught during Power Electronics subject in Year 3. The power converter that has been developed is the zero voltage switching (ZVS) with inverter voltage control mechanism. As for the microcontroller...
The non-linear devices used in the present environment like computers, printers, lasers, smps, rectifiers etc. pollutes the power system by harmonics and reactive power. Due to the presence of harmonics in the power system a number of undesirable effects caused in the distribution network. To find the solution for this the active power filter (APF) is one of the suitable solutions, which compensates...
This paper proposed an artificial intelligent control method for temperature control system and is suitable for low temperature applications such as laboratory equipments (e.g. ovens and incubators). The proposed design uses fuzzy logic as a control method that maintains the temperature of simulated heater to the desired point. Microcontroller based circuit is built to acquire data from sensor, actuate...
Maximum Power Point Tracking (MPPT) algorithm is widely used control technique that varies the electrical operating point to extract maximum power available from the solar cell of photovoltaic (PV) module. Since the solar cells have nonlinear i-v characteristics, the efficiency of PV module is very low and power output depends on solar insolation level and ambient temperature. Moreover there is a...
This paper presents a method to design a kind of power supply (PS) using PID (Proportional, Integral, and Derivative) controller. AVR microcontroller, atmega16 has been used in designing PS. Nowadays most of industrials systems use microcontrollers. PS is the integral part in each of them. A good idea is using these processors in order to generate the needed power for other parts of the systems. Especially...
The paper presents a Rapid Control Prototyping (RCP) toolbox for Matlab/Simulink, which can be used to generate real-time C code for the Renesas M32C87 microcontroller. The toolbox, Target for Renesas M32C87, contains Simulink blocks, which implement drivers and algorithms specific for the M32C87 processor, grouped in four libraries: I/O drivers, Digital Motor Control (DMC), Controller Area Network...
This paper dedicates a particular attention to pulse-width modulation (PWM) analog-to-digital ( A/D) conversion techniques underlining their importance in smart sensing systems. Nowadays, smart sensing systems and advanced signal processing techniques can improve measuring system's performance and flexibility relaxing hardware specifications and associated cost. The integration of sensing units, conditioning...
