The cost of design, implementation, and maintenance of a fault-tolerant control system are significantly higher than that of a traditional control system. Therefore, the only time that one can even think and justify of using a fault-tolerant control system is for safety-critical applications. How does a fault-tolerant control system increase the level of safety? This is the main subject of this talk...
The BP Deepwater Horizon oil spill disaster has reminded us, once again, the potential for systemic failures in complex engineered systems. But such systemic failures are not limited to the chemical and petrochemical industries alone. The 2003 Northeast electrical power blackout was a systemic failure. Financial disasters such as Enron, WorldCom, subprime derivatives market, and so on, also belong...
This paper describes an innovative concept for an advanced monitoring, control and diagnosis system for pumps. According to leading experts about 20% of the electrical energy used in industry is used for pumps and about 30% of this energy could be saved if intelligent control systems would be applied. In spite of this fact, currently very often no control at all is used. The causes for this low application...
This paper proposes a probabilistic safety management framework for control laws to reduce the frequency of events that a physical value in a control system deviates from its normal operating-range. This safety function is realized mainly by the safety ability to suppress the fluctuations of transient responses after a device failure in order to prevent the deviations from the normal operating-range...
Control allocation is a solution to distribute the control efforts among a redundant set. A new approach to manage the actuators redundancy in the presence of faults is proposed based on reliability indicators. The aim is to preserve the health of the actuators and the availability of the system both in the nominal behavior and in the presence of actuator faults. In degraded functional, a reconfigured...
