Lab Objectives • The objectives of this lab are: • Be able to download data from the automatic control system. • Be able to convert EEPromArduino data readouts to physical parameters. • Be able to calculate the supplied power to the AEV. • Be able to calculate the supplied incremental and total energy to the AEV.
Programming the AEV Controller AEV User Manual – System Analysis 1 • Follow Lab Procedure Guidelines to program the Arduino controller • Save Program • Run Program on Desktop stand • WAIT for MATLAB to process the data
Using the AEV Data Recorder AEV User Manual – System Analysis 1 • Open AEV Data Recorder program with MATLAB (aevDataRecorder.m) • Note: There is an updated version of aevDataRecorder.m on the course website under Project Documents. • Verify the AEV is connected to the computer • Run the MATLAB program to download the data • Open the data in the Excel Spreadsheet that MATLAB just created
AEV Data Conversion AEV User Manual – System Analysis 1 • The data recorded with the Arduino is in the form of integers that must be converted to physical parameters • Available data from Arduino includes: • EEProm Time (TE) • Current (IE) • Voltage (VE)
AEV Data Conversion cont. AEV User Manual – System Analysis 1 • Convert into the physical parameters of • Time (seconds) • Current (amps) • Voltage (volts) • Analyze the data by calculating: • Power (watts) • Incremental Energy (joules) • Total Energy (joules)
AEV Data Conversion cont. AEV User Manual – System Analysis 1 • A rectangular approximation of the power and time will be used to calculate incremental and total energy • There are 3 approximation methods:
AEV Data Conversion cont. AEV User Manual – System Analysis 1 • The midpoint method will be used by averaging the power of 2 neighboring points and multiplying by the time increment • Sum up the incremental energy for the total value used throughout the operation
System Analysis 1 Lab Lab Activity • Follow AEV Lab Manual and Lab Procedure Guidelines • Individual: • Create control program and test • Open AEV Data Recorder Program in MATLAB and obtain Arduino data • Analyze results
