176 Cyber-Physical Systems: From Theory to Practice
7.4 CLOSED-LOOP MODEL
With the anytime control algorithm presented in Section 7.3, any extra processing time available
is used to calculate additional elements of the tentative plant input sequence u(k). When compared
to the baseline algorithm (7.4), this provides a higher-quality result, that is, a control sequence that
better safeguards against performance loss at future time instances where processor availability may
be insufficient. The algorithm in Figure 7.2 amounts to a dynamical system that is driven by the
dropout process and the processor availabilities. We will next further elucidate the situation.
During each iteration of the while-loop in Step 3, the current state estimate ˆx(k) (see ...
