I am wondering what control paradigms are used by Boeing and Airbus to translate pilot settings (i.e. ![]() trim), accelerometer and gyroscope data from the IMU, and feedback from the aircraft's control surfaces to re-adjust said control surfaces. how could a PID system handle feedback from a gyroscope and Airbus side stick at the same time)? Would a simple PID controller suffice? If so, how would a single PID system be able to manage feedback data from different sources (i.e. However, how can computer hardware from the 80s (such as the Intel i386) be able to sample data quickly and compute Kalman filter within acceptable response times? I understand that the accuracy of PID systems are fully dependent on the feedback they receive, so I would assume that software methods of error correction like Kalman filter would be employed. ![]() I appreciate all answers, and I apologize if my questions require analyzing proprietary technical documents.Īs others have commented, you've underestimated how fast an Intel 80186 found on an early A320 is. ![]() The A320's first flight was in 1987, here's what the Air Force Flight Dynamics Laboratory had to say about the subject (Theory of Closed Loop Flight Control Systems) 20 years earlier: While it's very slow compared to what's available nowadays, that's still 6-25 million cycles a second. The electronics field has miniaturized even more so. Microelectronic circuits enable mixing, blending, voting, and, in general, response shaping to be done on a relatively small number of easily replaced cards. Metal oxide semiconductor (MOS) techniques decrease the size of these components by several orders of magnitude. Using these techniques it is now possible to redundacize electronics at a functional module-level with a resulting decrease in size, weight, and cost and a net increase in system reliability.
