Dynamic Error Budgeting

The performance of precision machines is mostly limited by the disturbances that are injected in these machines. These disturbances are often stochastic in nature. Dynamic Error Budgeting is a method whereby the effect of these disturbances on the final performance can be calculated. The advantage of this method is that it enables the designer to enter the contributions of the individual disturbances and view and optimize the overall machine performance. You can use Dynamic Error Budgetting to effectively design ulta-high precision machines.

Use Dynamic Error Budgeting to design ultra-high precision systems

You can open the Dynamic Error Budgeting tool in the 20-sim Simulator. This tool allows you to enter disturbances (as power spectral densities) at any point in your model. For each disturbance you simply have to select a corresponding model variable and define the noise properties. By selecting the output you can inspect the results of these disturbances at that specific output.

The Dynamic Error Budgeting Toolbox of 20-sim 

In the graph at the bottom right you can see the resulting error at the selected output as a result of the disturbances. The error is given in the form of a power spectral density (PSD) and cumulative power spectral density (CPS). The square root of the final value of the CPS is equal to the standard deviation of the output error. The standard deviations are shown in the Output Sigma tab.

The Dynamic Error Budgetting tool is part of the Frequency Domain toolbox of 20-sim.
