Abstract: In a parameter-dependent control system, comprising at least one controller, from at least one input value, taking into account at least one parameter, and a controlled system, to which at least one control value is fed, an optimization of the parameters of the controller can be achieved with the following design stages of an optimizer. An analyzer 11 connected to the control system for analyzing the control output. A simulator of the control system is connected to the analyzer, and an optimizer connected to the simulator for at least one parameter of the controller under given optimizing criteria. A parameter setter is proruded for setting at least the one parameter, which is optimized by the optimizer and determined in the simulating at the controller.

Abstract: A method for testing a network setup with a plurality of computers, in particular controllers or microprocessors, the data of which is to be transmitted and, if appropriate, received over a data path and which is to be processed by a control, priority criteria being established for the competing transfer of the data on the data path. A method of testing the network setup is proposed in which data signals of the controllers or microprocessors are generated with a realistic frequency and are subjected to the priority criteria and in which it is determined after what time data of certain priority levels can be transferred over the data path.
