Abstract

Mechatronic systems are characterized by replacing mechanical, hydraulic or pneumatic components by electrical and electronic components and programmed controlled functions. They offer a relatively flexible design with extended functions. However, the failure behaviour of sensors, electronics, actuators and software is disadvantageous compared to the failure behaviour of pure mechanics. An introduction first considers the status of fault-tolerant systems with mobile applications and computers. Some basic fault-tolerant structures with hardware and analytical redundancy for sensors, actuators, electronics and software are described including their degradation behaviour. Then, some examples of realized, fault-tolerant systems are considered as, e.þinspaceg., fault-tolerant electrical drives, electrical and hydraulic actuators, and sensor systems for mechanical quantities. The applied fault-detection methods and the reconfiguration are described. Herewith is it shown how the function can be maintained with only small disturbances of the operation after appearance of faults.
