摘要：Although it is widely accepted that every system should be robust, in the sense that "small" violations of environment assumptions should lead to "small" violations of system guarantees, it is less clear how to make this intuitive notion of robustness mathematically precise. In this paper, we address the problem of how to specify robustness in temporal logic. Our solution consists of a robust version of the Linear Temporal Logic (LTL) fragment that only contains the always and eventually temporal operators.
