Abstract
As computational technology advances, more and more systems in daily life are controlled or supported by algorithms and computers. The most representative evolution includes the fly-by-wire and the drive-by-wire of aircraft and automotive systems which are no longer pure mechanical systems. This kind of systems combining computations and physical behaviors are called cyber-physical systems, where “cyber” represents the computational part, and “physical” represents the physical behavior. Besides aircraft and automotive systems, other common cyber-physical systems include medical devices, smart grids, and robotics. Many of them are safety-critical systems, and a fault may cause serious consequences or even endanger users in extreme circumstances.
