    摘要: The invention refers to a method for computer-aided control of an automation system (100) by use of a digital simulation model (SM) which simulates the automation system (100) and which is specified by a number parameters comprising a number of configuration parameters (CP) describing the configuration of the automation system (100) and a number of state parameters (SP) describing the operational state of the automation system (100). Simulated operation runs of the automation system (100) based on the simulation model (SM) can be performed with the aid of a computer, where a simulation run predicts a number of performance parameters (PP) of the automation system (100). The following steps a) to c) are performed at each processing event (PE) of a plurality of successive predetermined processing events (PE) during the real operation of the automation system (100). In a step a), the values of the number of state parameters (SP) of the automation system (100) in real operation are sensed and a simulated operation run based on the simulation model (SM) specified by the number of configuration parameters (CP) and the number of sensed state parameters (SP) is performed. In a step b), if one or more predetermined performance parameters (PP) predicted by the simulated operation run in step a) do not fulfil a performance criterion (PC), the simulation model (SM) is adapted by changing one or more predetermined configuration parameters (CP) such that the one or more predetermined performance parameters (PP) predicted by a simulated operation run based on the adapted simulation model (SM) fulfil the performance criterion (PC). In a step c), the predetermined configuration parameters (CP) of the automation system (100) in real operation are adjusted to the changed predetermined configuration parameters (CP').

    摘要: A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which, is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θ base) of the model parameter. The updating vector (d θ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than "0" and less than "I". The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).

    摘要: A plant control includes determining a control input into the plant to cause a control output of the plant to converge to a desired value. A value of at least one parameter for adjusting a speed of change of the control output relative to change of the desired value is determined in accordance with a plant condition. The control input is determined based on the parameter having the value thus determined. The parameter includes a first parameter for changing a speed of change of the control input relative to change of the desired value. The parameter can also include a second parameter for changing the relative speed via a corrected desired value that is determined by correcting the desired value. The second parameter can further include a gradient parameter and a gradually-approaching characteristic parameter.

The ECU also sets an amplitude setting value in accordance with the cam phase, an engine rotational speed, an oil pressure, and an oil temperature.
