Week 2
- Rens and Jeroen conducted an FRF measurement on the left pizza robot. They did a closed loop measurement on each axis by applying a sin-wave + white noise to the plant. The sine wave is added to overcome the massive friction. The controller used in the closed loop measurement is tuned very low. During the FRF measurement the following data is collected: the input signal (u), the white noise signal (w), and the output voltages (v). With this data we calculated the process sensitivity and the sensitivity and to obtain the plant we divided them (similar as we did during the Motion Control course). We are uncertain if the left and right pizza robots have a similar plant so perhaps we should repeat the FRF measurement on the right robot because that one has the pizza racks on it.
Week 3
- We decided to use PID controller to control the pizza robot because we all have the most experience with them. This week we evaluated the FRF measurement data and loaded this in the programme ShapeIt. Because the right pizza robot broke we were not able to do more because we scheduled testing time on that robot.
Week 4
- We designed four controllers for each axis with a bandwidth of approx. 10Hz. We also obtaind all the positions to pickup the pizzas. With these positions we start to constuct the optimal trajectory.
