Procedure for three-level controller for e.g. rudder machine

摘要

In the procedure for adjustments of a mechanical system, the positions and the overrun of the mechanical system are measured and stored at specific intervals by a suitable sensor (21) and are taken into account in the generation of the next adjustment signal so that the controller has an adaptive behaviour.The overrun of the mechanical system is measured separately for two directions. The values determined are stored in a data memory and separately taken into account in the generation of the next adjustment signal.An error integrator additionally adds up the remaining residual errors and the added-up error is taken into account in the generation of the next adjustment signal(s). The error integrator is reset by signal (RESET signal) and the summation process is stopped as long as an adjustment signal is active. The time constant of the summation process is changed as a function of other signals and operational sequences, with the influences specified either acting singly or in combination on the integrator.
