System safety is the practice of ensuring that complex systems operate correctly and do not cause harm. It involves identifying potential problems and taking steps to prevent accidents or failures.

#Active Fault Detection

Active fault detection is a method used to find faults in systems while they are running. It can be split into two parts: finding problems passively and designing actions to gather more information about these problems.

#Passive Fault Detection

Passive fault detection means observing a system to find faults without actively changing anything. This method uses existing information to locate issues efficiently.

#Control Input Design

Control input design is the process of planning how a system should react to information it gathers. This helps systems respond better and improve their ability to detect faults.

#Barrier Certificates

Barrier certificates are tools used to verify the safety of a system. They help distinguish between safe and unsafe states, ensuring that the system does not enter dangerous conditions.

#Closure Certificates

Closure certificates build on the idea of barrier certificates and focus on transitions between states. They help ensure that systems can safely move from one state to another without encountering problems.

#Conclusion

Ensuring system safety is crucial for preventing accidents. By combining methods like fault detection and verification tools, systems can be made safer and more reliable.
