A lookup table is an array of data that maps input values to output values. You can use a lookup table to model your system. Estimate table data in the Parameter Estimation tool using data measured from your system. The estimated table represents a static system.

The behavior of actual physical systems often varies with time due to wear, environmental conditions, and manufacturing tolerances. Useadaptive lookup tablesto model the time-varying behavior of physical plants. Adaptive lookup table values update dynamically with incoming input-output data as the model is simulated.
