University Dynamics and Controls: Closed-Loop Systems Report

This report investigates control systems in electronic devices, focusing on closed-loop systems and their stability. It begins with an introduction to vibrations, control systems (open and closed-loop), and the ECP model 210 and 205 systems. The report then details system modeling for both rectilinear and torsional systems, including equations of motion and transfer functions. Experiments are conducted on proportional-based position control for rectilinear systems, PID-based position control for rectilinear systems, proportional-based control for torsional systems, PD-based position control for torsional systems, and speed control for torsional systems. The results are presented with graphs and analysis of parameters like overshoot, rise time, and steady-state error. The discussion analyzes the effects of PID parameters on system performance and why PD control is used instead of PID control in some cases. The report concludes by emphasizing the importance of control systems, the benefits of negative feedback, and the impact of different controllers on system response. References to relevant literature are also provided.
