1. Part 1- Lab report, structure and marking scheme

The first part of your report is around your laboratory work. It should comply with the following structure and will be marked based on following marking scheme.

Provide a brief introduction to rectilinear, ECP210. Explain the main objectives of the experiment.

Plot transient responses for a system ECP210 with one trolley using Matlab script "ECP_rectiliniear_data_step_input_oneTrolley.m" from the folder "Laboratory Experiments: Open-Loop Experiments with ECP210 and ECP210" on BB ENGT 5201.

o NB: Enter the name of file` with the data you collected during experiment:
o D = readECPdata(`name of file`);

Explain trolley transient process response to the step control input. Measure the overshoot, the rise time, the settling time using functions for editing in the Matlab figure.

Identify the physical parameters of the trolley-spring system (1DoF) using the approach described in this hand note

Attach the air dashpot to the trolley and tune its valve screw to reduce the overshoot and provide critical damping to the system. Save and plot several transient processes. Give the explanation to the observed results.

Connect a second trolley using additional spring. Apply a sine sweep control signal and run the vibration test. Plot amplitudes for two trolleys using Matlab script "ECP_sine_sweep_input_twoTrolleys.m" provided on BB (enter the file name with your experimental data). Explain the origin of two peaks in the system response.
