Nonlinear Vibration in a rotary Inverted pendulum – Sharif University. Date: Sep 2022
Brief description:
This project aimed to study the vibratory responses of a rotary inverted pendulum (RIP) with a full-state feedback controller. The team derived an accurate 2-DoF mathematical model using Lagrange’s equations and used the perturbative method of multiple scales to obtain an analytical solution to the nonlinear motion equations of the closed-loop system. The study found resonances at the first and second vibrational modes, resulting in moderately large-amplitude vibrations that must be avoided when adjusting the system’s time-varying set-point. The analytical results were verified through experimental measurements. The findings highlight the importance of understanding vibratory responses of dynamical systems to prevent instability in closed-loop stabilized systems.
Oven Controller – Rahavard Company. Date: Jan 2018
Brief description:
The project involved designing and prototyping an oven controller, which required a combination of electrical and mechanical engineering skills. The process involved designing a printed circuit board (PCB), programming a microcontroller to monitor and regulate temperature, and designing the mechanical parts necessary to connect the controller to the oven. The completed prototype successfully regulated temperature and had potential real-world applications. This project demonstrated the intersection of electrical and mechanical engineering skills in innovation.
Stadium Billboard – Segam Electronic Company. Date: Sep 2012
Project description:
The Iranian Track and Field Federation commissioned the installation of a billboard to accurately display the real-time finishing time of athletes as they pass the finish line. To ensure the accuracy of the display, the billboard was synced with an ALGE photofinish device, which allowed the display to show the real-time timer. Additionally, the issue of displaying the numbers on sunny days was addressed by incorporating a LATCH IC circuit. This circuit ensured that the numbers were clearly visible even in bright sunlight. As a result, the billboard was able to provide accurate and clear timing information to spectators and officials during track and field events.1
Timer Synchronization. Swimming pool: Date: Aug 2013
Project description:
The project was focused on improving the accuracy of timing for swimming events. To achieve this goal, we needed to synchronize the ALGE timing system with the sensors that were attached to the swimming plate. The swimming plate is a special device used to measure the time taken by athletes to complete a lap or a full race.
To ensure that the sensors were able to function effectively in the environment around the swimming pool, we had to take into account the high humidity levels that are typical in these settings. This required careful selection of components and materials that would be resistant to moisture and corrosion, as well as thorough testing to verify that the sensors would continue to function reliably even in the presence of high humidity.
Overall, the project was successful in achieving its goals, and the synchronized timing system with accurate sensor readings greatly improved the precision and fairness of swimming competitions in Iran.
Double Inverted Pendulum. Date Sep 2022.
Project description:
The project involved building a double inverted pendulum, which is a complex physical system consisting of two pendulums mounted on top of each other and free to move in two dimensions. The system was built upside-down and required advanced control algorithms to stabilize and prevent it from falling over. The project provided valuable insights into the behavior of complex physical systems and the potential for using advanced control algorithms to control them.
