Response Time Driven Design of Control Systems
(2014) 19th IFAC World Congress, 2014- Abstract
- A correct design of controllers must necessarily account for the schedule of the controller task over the processor. Existing design techniques are based on the assumption that there is no delay, or the delay is constant over time. However, in practice, almost all controllers have time-varying delay, hence invalidating this assumption. In this paper, we introduce a period design policy, in which the controller delay is modelled by the distribution of the task response time. We show, via simulation, that our method can reduce the control cost compared to the state-of-art methods.
