摘要:
We describe apparatus or a programmable logic platform for controlling a complex system. There is a processor, a plurality of inputs coupled to the processor for providing input data from the complex system to the processor, a configuration database coupled to the processor wherein said configuration database defines a plurality of logical operations to be performed on said plurality of inputs, said plurality of functional operations comprising a plurality of logical operations, and a plurality of outputs for outputting data from the processor wherein the output data is determined based on the plurality of functional operations which have been performed on the input data and wherein the output data is used to control the complex system. The configuration database comprises a set of truth tables which define all the plurality of operations and each truth table has thirteen or fewer inputs whereby the operations are exhaustively testable.

摘要:
An active vibration absorber is provided for absorbing vibrations in a member. An inertial mass is mounted on the member with a stiffness between the member and the mass. A force actuator arrangement applies a force between the inertial mass and the member. A damping arrangement provides for damping of a resonance of the active vibration absorber. A first sensor arrangement provides at least one first signal indicative of at least one movement and/or stress related parameter for the member and a second sensor arrangement provides for at least one second signal indicative of a reaction of the inertial mass. A control arrangement is provided for controlling the force actuator arrangement using the at least one first signal and the at least one second signal.
