System and method for determining the parameters of a controller

A method for determining parameters of a controller for a controlled system including a computer executing a control program, a simulation model being previously determined for the controlled system and the parameters of the controller for the controlled system being identified based on detected input and output signals of the controlled system, the method comprising:

• forming the controller as a model slave controller having a pilot control process and a slave controller, the slave controller for the controlled system being arranged downstream of the pilot control process for the controlled system including the computer executing the control program, the pilot control process including a master controller which is arranged in a feedback loop of a model control loop within the pilot control process and including the previously determined simulation model for the controlled system;
• defining a simulation model in the pilot control process based on the previously determined simulation model and identified parameters of the controller for the controlled system;
• defining parameters of a Proportional or Proportional-Differential controller as a master controller in the pilot control process based on a first model-based design method and the previously determined simulation model;
• and
• defining parameters of a Proportional-Integrated or proportional-integral-derivative controller as a slave controller for the controlled system arranged downstream of the pilot control process of the controlled system based on a second model-based design method and the previously determined simulation model.

A non-transitory computer-readable medium encoded with a computer program which, when executed by a computer, causes determination of parameters of a controller for a controlled system, a simulation model being previously determined for the controlled system and the parameters of the controller for the controlled system being identified based on detected input and output signals of the controlled system, said execution comprising:

• forming the controller as a model slave controller having a pilot control process and a slave controller, the slave controller for the controlled system being arranged downstream of the pilot control process for the controlled system including the computer executing the control program, the pilot control process including a master controller which is arranged in a feedback loop of a model control loop within the pilot control process and including the previously determined simulation model for the controlled system;
• defining the simulation model in the pilot control process based on the previously determined simulation model and identified parameters of the controller for the controlled system;
• defining parameters of a Proportional or Proportional-Differential controller as a master controller in the pilot control process based on a first model-based design method and the previously determined simulation model;
• defining parameters of a Proportional-Integrated or proportional-integral-derivative controller as a slave controller for the controlled system arranged downstream of the pilot control process of the controlled system based on a second model-based design method and the previously determined simulation model.
