Hi, i am starting entering on the fixed wing VANT reasearch field, and i was browsing the options for the control system architecture. I could find two possible ways i could go. A TMS570 microcontroller + Some safe RTOS (SafeRTOS, =ECC/OS-II...), or a PC104 (with non defined processor architecture) + QNX. In most of the cases the last is the one that got much more horsepower, but still is heavy, bulky and will probably have a worst RT response than the first one. However the first one got a very limited processing power (180Mhz frequency), so am not sure if that is going to be enough for now. I belive t will, as i will have a separare processor for the AHRS system.
Any comments or sugestions regarding this architecture? Any one with know-how on the field?
Thank you!
