Hi, In our research group we are working in designing control algorithms for Power System. By now we've using DSP based systems, we are interested in moving to a PC based system, so we decided to study if RTLinux is a good option for as. Our task are periodic with T=20us-50us depending on the specific system. We have developed a very simple periodic task in order to obtain a square wave over the parallel port. In this experiment we notice that there's a jitter which varies for 3-5us. This would reduce over algorithm performance. I have the following questions : -Do you think RTLinux is fast enough for this kind of task ? Does anyone have experience in using RTLinux with this kind of systems ? -Could we reduce the jitter through the variation of the scheduler timer tick size ? (Which is the jitter source ?) - Using a faster machine would reduce the jitter ? -If we put our control algorithm in the ISR of a periodic interruption, which kind of jitter would we have ?
