Preparing an Optimization

1. In the Optimization Options area, from the Optimization Algorithm drop-down list, select the desired optimizer.

   For more information, see Optimization Algorithms.

   

2. In the Number of Iterations field, enter the number of iterations you want to run.

3. To adjust additional optimizer options, click Configure.

   For more information, see Optimizer Options.

4. In the Optimization Criteria area, follow these steps:

   

   1. In the first drop-down list, select the function output you want to optimize1 e.g., TorquePredict.

   2. In the second drop-down list, select the respective imported data channel or function node2 e.g., Torque_Meas.

      The flat parameters results in a high RMSE. After the first optimization, the RMSE will be significantly reduced.

   3. If desired, add another optimization criterion.

5. In the Local Constraints area, click to add a local constraint.

   

6. In the first combo box, select the channel or function node you want to limit.

7. In the second combo box, select a comparison operator.

8. In the third combo box, select the channel or function node to be used as limit.

   Note
   You cannot directly enter a number <n> as limit. To use a number as limit, create a function node <node> with expression <n> and select <node> as limit. Alternatively, you can create a scalar parameter which is not optimized and use it as limit.
