Manuscript for IEEE Transactions on Automatic Control 22 can say that AC-S is a robust policy to keep the system from behaving divergently and degrading performance significantly as have shown in the previous stability analysis.

In the deterministic environment the system behaves stable under AC-S while diverging under AC- N. But, it is not valid in the stochastic environment because the system seems more stable under AC-N. This might explain partially why AC-S does not perform better in stochastic environments. 1720 1710 Optimal T 1700 1690 1680 1670 1660 1650 AC-S (Con2) AC-N (Con2) AC-S (Con1) AC-N (Con1) 1640 0 200 400 600 800 1000 1200 1400 1600 1800 Time Fig. 9. Behavior of T * in unstressed environments
Manuscript for IEEE Transactions on Automatic Control 23 The system controlled by adaptive control policies is naturally adaptive to changing environments as components monitor their environments and incorporate them into the decision process. As shown in Fig. 10 and 11 for deterministic case and Fig. 12 and 13 for stochastic case, when environment changes the system adapts to the new environment. 4000 3000 Optimal T 2000 1000 0 0 200 400 600 800 1000 1200 1400 1600 1800 2000 Time Fig. 10.
