Greetings,
I am working through Section 5.2 Driving the Rover using Open-Loop Control of the AEK Rev 2. Encountered an issue.
I ran the dc motor characterization script and saved motor responses for Left and Right motors independently in a new mat file. I am able to properly implement the values into the lookup table for each motor with no issue. However, when I run the model I am getting a humming noise from each motor as though the commanded speed is not enough to get past the dead band of the motors. This is strange because as is, there are gain blocks with a gain equal to 100. I had to add additional gain blocks and add arbitrary values of at least 10 to even get close to the wheels spinning at a perceived equal rate. Although it really doesn't spin at equal rates by a lot.
What is the issue. Has anybody else encountered this?
