This example uses the same response data as the previous system. Comparison to existing methods shows that the proposed procedure yields better reduced models. open in overlay Copyright © 1990 Published by Elsevier Ltd. check over here

Consider the error response of a second order system. However, you can do simulations or measurements, and you can get a value for the IAE, and you can compare IAE valules for different systems as a way to evaluate those When tested with a random input, the reduced models derived from impulse response deviations outperform those designed to minimize step response deviations.

  • In this game it is necessary to provide a score, and to provide a score we needed some measure of how well the player was able to control the system.

We can conclude that this would not be an effective measure for this system. http://madeleinebrand.com/integral-square/integral-square-error-pdf.html The first temptation is to just integrate the error.

In other words, it might be OK to have a large error for a short time if that helps you keep the error very small at all other times. Forgotten username or password? However, when the system responds there will be times when the error is large (like when a request for a step change in speed arrives), but that the error will get this content JavaScript is disabled on your browser.

After all, a negative error is just as bad as a positive error.
