Idle Speed Control and Air-Fuel ratio Control of an Internal Combustion Engine
- Built a Simulink model of a 4-cyl 2.4 L engine to model a plant in discrete domain.
- Optimized the throttle angle to maintain an idle speed of 800 rpm using a SISO controller.
- Developed and tuned a PID controller for the idle speed control and achieved zero steady state error.
- Utilized Root Locus techniques to develop a controller to compare with the results of PID control.
- Developed a SISO controller to maintain the Air-Fuel ratio.
- Designed and simulated stress analysis of a scaled down version of a wing.
- Obtained a performance function using Two-point Adaptive Nonlinear Approximation (TANA).
- Calculated the reliability of the wing using Monte Carlo Simulations, Mean Value First Order Second method and Hasofer Lind - Rackwitz Fiessler method.
- Calculated the forward kinematics and the velocities of the four serial manipulator links (limbs).
- Designed a three finger centric gripper based on the parallel manipulator model (hands) using SolidWorks.
- Utilized the parameters used for the kinematic calculations, a CAD model of the robot was created.
- A set of Euler Lagrange equations were created to simulate the dynamics of the limbs.
- Created a MATLAB code to simulate the dynamics of the two link robot.
- Tested different initial conditions and plotted the link responses and phase space trajectories.
- Implemented a PD controller for the system using control torques which are calculated using gains.
- Simulated the closed loop system using different sets of initial conditions and plotted the link responses and the tracking errors.
- Created a layout of an assembly line that incorporated eight industrial robots.
- Applied the concept of Petri Nets to the assembly line and described the layout with their properties.
- Predicted the future states of the system using matrix representations and the analysis methods.
- Vane calculations on the existing impeller model were done and the optimum blade angle was found out.
- Performed Static testing using Hypermesh and Radioss and CFD analysis performed using ANSYS-Fluent.
- Eliminated the need to build prototype impellers for testing.
- Worked as a part of a team that designed and built a tubular, off-road vehicle as a leader of the suspension team.
- Calculated spring length and travel and optimized the camber, castor and king-pin angles.
- Designed the suspension system in SolidWorks and simulated the model using Lotus suspension software.
