ASCMO-DYNAMIC ExpeDes

ASCMO-DYNAMIC ExpeDes is a tool for creating experiment plans based on Design of Experiments (DoE).

Design of experiments is a method for data-based modeling of unknown systems. At the beginning of the modeling is the experiment plan with which data are obtained for the model training using a minimum measuring effort – this data record is subsequently used to train the model. The models, in turn, are based on mathematical approximation methods and are capable of reproducing the behavior of the measured system.

Goal of the modeling is the evaluation and optimization of the system behavior, e.g. for an internal combustion engine the determination of the input variables that lead to optimal output variables (maximum performance, minimum consumption/emission).

ASCMO-DYNAMIC ExpeDes Working Steps

Working with ASCMO-DYNAMIC ExpeDes contains the individual steps for creating an experiment plan:

  • Starting ASCMO-DYNAMIC ExpeDes

  • Step 1: General Settings

    This is the first step in which the number of measurements and the number and configuration of the inputs is defined for the experiment plan.

  • Step 2: Constraints

    In this step, constraints of the measurement range can be made for a variable.

  • Step 3: Input Compression

    In this step, compressions of measuring points in certain areas of the measuring space can be specified for inputs by area.

  • Step 4: Steady State Points

    This step allows you to define operating points for the system, which have a frequency of stay in the experiment plan. In addition you can define steady state phases and the duration of the steady state phases.

  • Step 5: Block Configuration

    In this step, the experiment plan can be divided into several parts (blocks) that can be measured separately. Each block by itself corresponds to the requirements of the design of experiments and is space filling.

  • Step 6: Snippet Configuration

    This step allows you to include external cycles into your experiment plan.

  • Step 7: Calculated Inputs

    This step allows to add and specify additional inputs calculated from formulas.

  • Step 8: Export

    In this step, the properties of the project and the experiment plan itself are displayed which can be exported to a file at this point.
