What is integral square error?
[′int·ə·grəl ¦skwer ‚er·ər] (control systems) A measure of system performance formed by integrating the square of the system error over a fixed interval of time; this performance measure and its generalizations are frequently used in linear optimal control and estimation theory.

What is ISE IAE and ITAE?
The generally used performance criteria in stability analysis includes Integral time absolute error(ITAE), Integral square error (ISE), Integral time square error(ITSE) and Integral absolute error (IAE).
What is ISE and IAE?
1. Integral Square Error (ISE) 2. Integral Absolute Error (IAE)
What is IAE error?
IAE integrates the absolute error over time. It doesn’t add weight to any of the errors in a systems response. It tends to produce slower response than ISE optimal systems, but usually with less sustained oscillation. ITAE integrates the absolute error multiplied by the time over time.
What is ITAE error?
INTEGRAL TIME ABSOLUTE ERROR (ITAE) METHOD. Integrates the absolute error multiplied by time over time, it weights errors which exist after a long time much. more heavily than those at start of the response, its relationship is[4]: (4) ITAE produces system with settling time much more quickly than the above two methods …
What is Integral absolute error?
Integral Absolute Error. The sum of areas above and below the setpoint, this penalizes all errors equally regardless of direction. Integral Squared Error. Penalizes large errors more than small.
How do you calculate SSE and MSE?
MSE = [1/n] SSE. This formula enables you to evaluate small holdout samples. Root Mean Square Error.
How do you square a function in MATLAB?
x = square( t ) generates a square wave with period 2π for the elements of the time array t . square is similar to the sine function but creates a square wave with values of –1 and 1. x = square( t , duty ) generates a square wave with specified duty cycle duty .
