Summary Report
Type-A
- Replaced the SG board for the LVDT drivers with a new board in IY. The oscillator signal became stable. The old board seems to have a break in the circuit.
Type-B
- For the BS, Terrence and I have been calculating the IP-L sensor correction and blending filters. Terrence had new ideas for updating the calculation of the filters, and it was worth trying. I aim to test the results next week.
Type-Bp
- For PR3, I added the inter-calibration factor and the BF Damper sensor correction filter. The sensor correction is enabled when the suspension goes through ENGAGE_STRONGDAMP state.
Type-C
Electronics
Control
Schedule
- Type-A: IP control with ACCs.
- Type-B/Bp: BS sensor correction and blending.
