The invention relates to a method for adjusting at least one control parameter (KP) of an internal combustion engine () by means of at least two setting parameters (SP), having the following steps:

Method for adjusting at least one control parameter of an internal combustion engine

The invention relates to methods and devices for developing programs for process control systems and in particular for mathematically intensive or, as the case may be, mathematically complex programs of said kind. According to the prior art programs of said kind were written in a separate development environment and subsequently the developed algorithm was re-implemented using a programming language available for the process control system and the associated compiler. The programming and testing were consequently both time-intensive and prone to error. It is proposed to split the overall algorithm into two parts when programming programs of said kind, a) the actual control algorithm by means of which the mathematical functionality of a controller is provided, and b) the algorithm by means of which the process control system-specific functionality of the above controller is provided. The second algorithm referred to runs in the process-oriented component of the process control system and the actual control algorithm in a computer suitable for industrial application. In order to control the process the two algorithms exchange data, the decision-making authority remaining at the control system level.

The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (S ), representative of the currently arising vibrations of the chain ( ), from the operating data of the main and auxiliary drives (I, II) by means of a detection device ( ), and to take this to an active suppressor ( ), which generates a time-variable control signal (S ) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (S ) for the closing pressure adjustment of a multiple disc clutch ( ) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain ( ).
