Working Steps of ASCMO-STATIC ExpeDes

The following sections describe the individual working steps involved in creating an experiment plan with ASCMO-STATIC ExpeDes.

NOTICE
Damage due to wrong test plan Wrong engine settings in ASCMO-STATIC ExpeDes/ASCMO-DYNAMIC ExpeDes can lead to engine or test bench damage. Example: the operation point overstresses the engine and causes damage, e.g. by setting an ignition angle that causes extensive knocking. The general settings for the test plan must fit the system and the object. Negative example: 10000 rpm are set in the test plan vs. the motor has max. 6000 rpm. Limit the operation points to the allowed values. ETAS ASCMO does not have any knowledge about the engine parameters. Limit the engine load in the general settings before exporting the test plan. Verify the test plan for further use.

Damage due to wrong test plan

Wrong engine settings in ASCMO-STATIC ExpeDes/ASCMO-DYNAMIC ExpeDes can lead to engine or test bench damage. Example: the operation point overstresses the engine and causes damage, e.g. by setting an ignition angle that causes extensive knocking.

The general settings for the test plan must fit the system and the object. Negative example: 10000 rpm are set in the test plan vs. the motor has max. 6000 rpm.
Limit the operation points to the allowed values. ETAS ASCMO does not have any knowledge about the engine parameters.
Limit the engine load in the general settings before exporting the test plan.
Verify the test plan for further use.

For ASCMO-DYNAMIC ExpeDes see Step 8: Export and Step 1: General Settings.

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.

Visualizing the Experiment Plan

To be able to evaluate the plan data, you can display it either graphically or as a table at any time.

Step 2: Constraints

In this step, constraints of the measurement range can be made for a variable as a function of one or two other variables.
Step 3: Input Design Types

In this step, settings can be made to define how individual inputs are to be measured.

Step 4: Input Compression

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

Step 5: Sorting Rules

In this step, sorting rules can be defined for inputs so that the experiment plan is passed through in a meaningful way (according to the characteristics of the respective system).

Step 6: 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.

Step 7: Additional Points

In this step, points can be defined which, in addition to the points of the experiment plan, should be approached repeatedly according to specific criteria and measured, if necessary.

Step 8: Calculated Inputs

This step is skipped in this tutorial.

Step 9: Export

In this step, the properties of the project and the experiment plan itself are displayed. You can export the data in several formats. In addition, you can display the data as scatter plots, 3D plots or as a table; see Visualizing the Experiment Plan for details.
