Abstract: According to an aspect of the invention, a computerised system, in particular control system is provided, which is configured, from an input vector (In) which represents a discrete number of input variables and from a state vector (Zn) which represents a discrete number of state variables, to determine a new state vector (Zn+1) whose state variables are updated, as well as an output vector (On) which represents a discrete number of output variables, wherein the output variables are provided for controlling at least one appliance and/or for outputting information. The system comprises a plurality of computation units which in parallel determine the new state vector and the output vector from the input vector and the state vector. According to the invention, the system is configured such that at least all news state vectors are exchanged between the computation units after each cycle.

Abstract: An error tolerant computer controlled system comprises several computers working redundantly and controlling actuators based on signals from sensors and input devices. Each data item emitted by each computer is simultaneously sent through differing communication paths to each actuator, such that in normal operation each actuator receives each data item through several paths. This system continues to function properly even in case of a failure without requiring any re-routing of the data items, which makes it easier to design, analyze and test and thereby increases its reliability.
